[@jaidgreen75]

YOU TAUGHT IN 7 MINUTED WHAT I COULDN’T FIGURE OUT IN LIKE A WEEK THANK YOU

[@uzeyy]

Same

[@sorenseabrook791]

Same

[@chuchumint3384]

My teacher's been teaching this for 2 weeks now lmao

[@lordmomstealer]

Its 10th class topic in India education system

[@laurenjohnson1161]

Omg yes I literally sat on my couch trying to figure this out for hours this was crystal clear

[@alainarose4]

This man is great. Im a sophomore in college and he has been saving my ass on exams since i was a sophomore in high school. He's great for bio and chem too!

[@ethanpearson7060]

Your learning this in COLLEGE?

[@eoinreilly8477]

@UGHROHA sounds like GCSE

[@MK-oe5md]

I love this man. Seriously was so confused for an entire week, and he comes in and teaches it to me in less than ten minutes.

[@vikneshmaniam5618]

the analogies used in this videos are extraordinary

[@eraybulgaria]

You are an excellent teacher. You talk faster than the rest i have seen but you explain concepts clearly. Thank you very much for all of your work

[@EugeneKhutoryansky]

Thanks for making these videos.

[@supercrazpianomanaic]

Oh my god! It's the legendary Eugene Khutoryansky! Your videos are amazing!!!! Thank YOU for making your videos

[@abhishekbishnoitechnical439]

both of you ( team ) are also making good....your animated videos are very much helpful

[@lordmomstealer]

You are the quantum physics gay , I love you'r vedio.

[@jasmienmanak6514]

my life just became ten times easier. Thank you so much! I understand this concept completely now

[@Eaineain-v4k]

Hi I am a Myanmar girl and my name is Elina. I am 16 years old I am watching your videos right now and it is so amazing by your efforts and thank you for sharing your work with us

[@BITStudioCode]

OMG that refraction trumpet player analogy/example is legendary, never thought of that that way, got me to understand it better!

[@강아지-m5j]

The marching band analogy is just amazing.

[@erickcastellanos6814]

ugh im my 2nd year at UCI and this helped me out so much for my physics 52a lab. You were clear and concise in defining what refraction was. your analogy of the marching band was very helpful as well! thanks

[@rohanjobanputra1417]

Y'all learn this in 2nd year of college? We're taught this in 8th grade 😭😭😭 So lucky

[@cristinataylor-brell3407]

I was most worried about ray diagrams for my end-of-year exam... This made it seem so simple. Thank-you!

[@lordmomstealer]

Hy Cristina its 10th class topic in india education system. LoL

[@malaikabaig4929]

Finally understand! I have a test tmrw and this helped ALOT!

[@angelren6327]

Your teaching skills are so good. My son said he never saw so good physics teacher in China.

[@robertseitter3829]

I’m studying for MCAT physics and this was the only topic I was dreading. Thank you so much

[@naneeskhattab9630]

your videos and your way in explanation are amazing.Thank you

[@NotAshes_ily]

you taught me what my physics teacher couldn't thank youuu

[@MonsieurButter]

I couldn't figure out why a virtual image could be on the same side as an object thank you so much for the explanation

[@yadakkpolyt8132]

Thanx!!!! You explained material that on my classes I couldnt apprehend at first!!!

[@bobbob123ful]

Don't arrest me

[@skyfire299]

You mean comprehend

[@meraj95]

Visualize the working of convex lens on DESMOS. Its a web based application built for students. kzbin.info/www/bejne/gHulcn5_mreomLc

[@huangyipeng1108]

Hey Love your work, god bless, straight to the point and no meaningless chatter

[@Proven88]

I had to watch 7 videos before I found one that explained what happens at distances less than the focal length! Thanks!

[@Acd1992]

I'm preparing for the Physics GRE and these videos make for great refresher courses.

[@ЕвгенийЕжов-ц3к]

Thanks a lot, perfect explanation, even for non-english speakers!

[@leif1075]

HOW? He does really explain. what a virtual image is

[@rishiyk348]

concise explanation. youre the goat mr andersen!

[@edj_ph6213]

Thanks for being helpful as always. You make concepts chewable and palatable even to non-fans of physics. ;-)

[@ishaan6709]

Wait so diverging lens images are always virtual?

[@blakeking1125]

Mr. Anderson you are a God send.

[@sefofiwilliamlebea4071]

I rely on your videos sir. they are very different and so helpful! thank you very much wow

[@skhalomakofane4274]

After 3 years of watching your videos, i still call you Mr Bozeman instead of Mr Anderson.🤣

[@FernandoSanchez-ov3ji]

Wow even better than my teacher teaches! All my physics teacher does is making us watch a video every day and give us a worksheet in class and don’t even explain or teach how to do the problems and she says her job is to give us the 5 minute video every day and review in clan, but not explain, so I’m like aren’t teachers supposed to teach?🤬 I have the worst teacher ever but this video made mi understand a full week of class in just couple of minutes, thank you

[@funkyhaha11]

Great video, I found the diagram of the sliding object particularly helpful. Thank you so much.

[@baileyhaas6393]

Thank you so much!! I was really struggling, but I completely understand now!! thank you!

[@svijayiitk]

Thank you very much!!! I Understood everything in 7 minutes what I didn't understand in a week, literally! Thank you for making these videos😎😎😎. Subscribe instantly to him!!!

[@hrperformance]

Amazing video. This cleared so much up for me. Thank you!

[@lusianasutanto5863]

Mr. Anderson...I am nearsighted, wears glasses... but I think the object that I see is not diminished (or smaller than the real object), why is it different from the concave lenses properties?

[@guimartgon]

Hi Mr. Anderson! Do you happen to have anything on AP Chem? I just graduated from HS and I never took an advanced chemistry class and I want to at least have some extra knowledge before heading to college :)

[@matterxleben7306]

guimartgon I hope ur enjoying college

[@evdm7482]

wait, sorry, but is the virtual reality of the image creeping up behind you an abstraction of maths, or really Euclidean geometry? ie, can this be done in a real world experiment? Sadly AP wasn't always afforded to me... but thanks for the lesson

[@j.g.2248]

Thank you for making videos like these! I really appreciate it :)

[@haroldcandland9779]

I have a question (and I'm not even remotely prepared to handle any higher math) that will likely be hard to ask and even harder to answer. for context I am a high school drop out with very little knowledge of math. I do however have an imagination and google. So if I want to know what a "rate" is I can google it and learn that it is distance/time and work from there as i try to imagine something like a wheel accelerating and its velocity or whatever, just to give an example. I'm assuming the marching band members represent points along their respective rays and not photons, in the case above, the other closest marching band members respond to the first band member reaching the lens edge by turning toward the edge (ie before reaching the lens edge) is this just something that happened in the animation and not necessarily intentional, or is this an accurate depiction? if so, is this because as a wave it is affecting the light around it, such that at the first point there are "ripples" occurring which slow and change the "trajectory" of the next chosen position of a ray for measurement? I'm not even sure if "ripples" in a light wave can affect other light waves, I unfortunately cannot wrap my head around how something like an orchestra can be reduced to a single wavelength without becoming an average of each part and then sounding like a humm when you replay it, and so it may be that this is beyond my understanding too. but i just thought I'd ask either way.

[@geolegend6425]

Thank you very much! This has helped from failing my exam!

[@mkhatri007]

super amazing explanation and extremely helpful

[@johnschottler1424]

Simbucket was super helpful!

[@user-wy1ys8xf6l]

6:20 can anyone explain what the parallel line is, how do you know where that’s supposed to be

[@johannvaniperen7249]

thank you sooo much. I finally know how to properly draw a diagram and i have an exam in two days

[@danielmahmoudi6731]

great analogy with the sand!

[@anditsjen]

why wouldn't the ray go through the focal point left of the diverging lens? i know i can always draw three lines to confirm where the image forms. but i have a hard time understanding which focal point to use for different lenses, especially when double optics are introduced

[@misskwannie]

6 years later i hope you have an answer for me too

[@mkhatri007]

what simulation software you used?

[@shanecronin9636]

I am a little confused about why the light bends the way it does (or why we draw the arrows the way we do). Based on what I know from refraction, shouldn't the light bend once when it initially hits the lens, and then bend again when it leaves the lens? Why is it bending in the middle of the lens (and only once) where it's not changing from one medium to another?

[@t.dan-danlubarda3254]

You're correct, the light does bend twice. He was drawing one bend to make his life easier because he's calculating the total angle of refraction. In reality the light bends when it hits the glass then bends again when goes back into air, giving that total angle of refraction. The way he is drawing it does make it confusing.

[@AbdullahRushdi]

You are the best :) I watch your videos even those not in my syllabus

[@sweetdreams37]

Thank you so very much!!! This helped immensely.

[@thecoreybrown]

Hello, I have a question, at 6:18 how do you know to draw the second parallel line like that? Like, how far up or down to draw the parallel line? Thanks by the way. You've been helping me through my whole college career (6 years!)

[@OxzowachiAlt]

I have the same question lol

[@josemariaalipio449]

Brilliant tutorial. Thank you, Mr. Andersen.

[@brandonross5881]

This was helpful. Thank you

[@judydai6048]

So helpful

[@angelolvera6269]

Why can’t we use the focal point in the left for the last example?

[@dsa66253]

Excuse me. Consider a meniscus, which has curvatures of the both its side, meaning it's neither a positive meniscus nor a negative meniscus. What is that lens' ray diagram? Is that converging or diverging the ray of light?

[@krtdhi7007]

How do you decide the focal point on ray diagrams ???

[@taetae0310]

Amazing! You are the best!

[@calibr0636]

oh, i understand now. thanks man. i have an exam next week

[@dhlaminikamogelo6604]

why does the picture that is seen turns upside down ?

[@anitafan264]

cramming for my exams. This is just what I needed thanks man

[@sarahabte8298]

well structured

[@ivivibic]

For the object, does it have to be on 2F? can it be further than 2F?

[@ivivibic]

Is the image is not diminished if the object is on or less than 2F?

[@LyricZ]

I watched it before my physics exam...That was helpful.

[@adnanhepvar3]

Simply and perfectly explanatory. Thanks a lot!

[@JH-ux1re]

Very helpful!

[@aishaaisha7341]

Great teacher

In Which Video Dat Boi Was In?

[@__-xh3uw]

¯\_(ツ)_/¯

[@thinhse]

Could you tell which program you used to draw things? Very nice and sharp images. Thanks.

[@HiAdrian]

Very helpful, good information density. Thanks!

By the way...thank u so much for this video, it helps me a lot in understanding the material for the exam of grade 9...👍👍😆

[@balamuhammadsani9275]

thanks. your videos are really amazing, and you use to show how it happens in real life.

[@minesiperera1342]

THANKS A LOT SIR, THANK U VERY MUCH....

[@mrunknown6807]

You are a genius

[@Jervisbrentsarmiento.]

You thought me a lesson that was supposed to be discussed for a week into a 7 mins video

[@hannahjoycheng]

thank you i love this

[@neoray99]

Thank you for that video, it helped a lot

[@radwansalm5110]

Do you have translated videos for Arabic
