This guy is an absolute angel, my whole class is so loud that I'm not able to understand........Here he even teaches better and its sooo peaceful !!!!!!!!!! Thank you so very much!!!!!!!

[@emogoesboom]

indeed he's the reason why im passing phys lol

[@CatherineHayden-w9j]

I love this guy

[@moongaming9684]

He ain’t gonna let you hit bro

[@JustAcobrakaiFan173]

That's what really happens to me also ...

[@vejabeleckyte1319]

Thank you so much! I really couldn't understand anything in like 5 classes which all lasted 45mins yet you completely taught me everything in just 15mins. With some practice I'm definitely gonna nail that test tomorrow. I'm really grateful, thank you so much.

[@nashyrg3523]

Can you tell me what does he mean by Nx

[@lola100yearsago8]

What is critical formula please

[@paradice5495]

@@lola100yearsago8 the critical angle = the inverse of the nr divided by the ni. { critical

When you realize how much more you understand from YT videos than in actual school

[@tarbsmwale9093]

IKR dudeeee honestly i need to start paying THEM my money instead for this school..........

[@miscellaneous3372]

Is school a scam now? College is though

[@prabhanjanbag5738]

Your style of teaching is so simple and precise that one can learn the basic things of Physics even in a single video instead of wasting lots of time on others.

[@caseyredding6754]

you have saved my life in all of my science classes. thank u.

[@aliammar8517]

As a med student, and for some reason, i have to watch for my final physics exams Great explanation❤❤

[@gearmaker5123]

Thanks Mr you sure do help alot and I rely almost on you to learn all my lessons because you teach better than what I learn in school I hope that your channel grows and that you keep making these great videos.

[@samkeloinnocent8316]

You the best Mr Organic Tutor I wish you are my lecture, everything that I must know at varsity I learn from your videos.

[@eashafatima-s3d]

I can't describe how happy I am for discovering your channel. You made total internal reflection so easy. Thank you for this amazingggg video. Love from Pakistan

[@leonhardolaye-felix8811]

Thanks so much. Understood a 15 min video better than a two hour lesson

[@kosiokoye2384]

please do a video on refraction through a glass prism... will really need that.. thank you

[@jaisharma8212]

amazing video, extremely detailed and helpful. also love the slow pace

[@vonjoshuacaindoy7814]

thank you so much for this video. It really saved me for my test tomorrow!

I love your content, it is easy and simple to understand and has so much perspective...🔥🔥

[@polflames123]

literally have a test tomorrow about this topic it's my first test back since offline school, and i was kinda scared to see how it'd go, but i got more confident watching your video and understanding more about the topic. Thank you.

[@mjr8456]

Thank you very much. you helped me a lot. continue with the good work. i have now got a clear picture of critical angle, total internal reflection and even snells law

[@paradice5495]

tysm you really helped!! I'm having a physics final this Saturday and it helped me a lot!!

[@AOT288]

this nigga right here is saving my physics exam

[@kareemosama5373]

Pretty sure he's white 😅

[@echofoxtrot2.051]

This video is perfect for reviewing specific concepts I learned so as to prep for cumulative finals.

[@wanitta98]

taking the GAMSAT tomorrow, your videos have saved my life !

[@arulgk9673]

Good Luck!

hwo its goes :)?

[@paulokayed8860]

we want a name reveal simply due to the fact that you have saved many of us from inevitable failure

This guy can save the entire science class or stem classes.

[@mohammedfathy1716]

So in Summary, The lights totally reflects only from mediums of higher index of refraction. The mathematical definition of the critical angle is the angle, at which the calculated angle of refraction is 90°. The critical angle is associated only to a pair of mediums and it is the angle, after which the lower index medium starts reflecting light coming from high index medium.

[@geogaddi84]

very elegant method for critical angle. cheers, sir

[@OnlyOne1Dee]

Sir you the best. To be honest i understand physics through your explaination. Thank very much sir

Holy shit… I’ve been trying to understand this for the past week as my teacher couldn’t. As always, thank you for saving my ass, I’ve got a test tmr.

[@Keisuke-f7e]

Thank you so much for this vid! It's actually so helpful and way efficient than my 45mins physics class in school ^^

[@okudayemartin8965]

Yeah

[@vivoatef8690]

You're such a lifesaver ♥️♥️♥️

[@fatallasalama]

14:00 I think you were mistaken here The index of the air should have been accompanied with the angle of incidence (40) not the angle of refraction (90) so the equation is n1 sin40 = n2 sin90 n2 will equal 0.642

[@yankeeklu7909]

Thank you finally got to understand it.

[@WO0PSY]

thanks to u i got 100 on my exam

[@antonioruelas8902]

Currently studying for a physics exam. In example #4, since glass is equal to 1.5 and water is equal to 1.33 (therefore glass has a higher index of refraction than water), shouldn't glass have an angle of 90 degrees and we should solve for the angle on water?

[@shanaaze]

you are a life saver !!! thanks so much xx

[@Koltary]

do we have to know how much it refracts from less dense to more dense medium or do we just make a ray that is obviously closer to normal plz tell me i have an exam tmrw

[@TheOrganicChemistryTutor]

The drawing doesn't have to perfect. If the light ray travels from a medium with a low index of refraction to a higher one, the second ray should be drawn closer to the normal line.

[@Koltary]

ok thanks

[@salmanshakeel2483]

Great video

[@vivoatef8690]

Thank you professor your explain is so good ♥️♥️

i love you organic chemistry tutor

[@abo5n]

Can you employ the phenomenon of total reflection or refraction to identify the percentage of a pollutant in water? Discuss this by designing a experimental model.

[@AfafKhalid-y5f]

Wooooow, very nice❤

[@rishimishrq9384]

Some video of optics plz

[@princesspat5239]

Im French and well what does interface mean ? Btw amazing videos I love them

[@DapaChrons]

in this problem it just meant a meeting place between two things, so between a solid and air Generally it means something that allows you to communicate with a computer, like a "computer interface"

[@y22-t4t]

thanks for teaching❤

[@eduardomoreira7624]

Once again I'd like you thank you

[@DK-23-]

i have a question, how do you know for the last question that the light went from solid to air and not air to solid, before doing the problem

[@faizalkevin1937]

Thanks so much

[@panaskourris2272]

thanku so much man❤

[@yousif8595]

thank you very much vielen Dank شكرا جزيلا

[@YxngOne_]

Thanks a lot really helped meb

[@jesusmrosario-claudio4104]

Thank you once again.

[@xanderbulter-davies5800]

Life saver mate

[@lisak6343]

For the second question, I had put solid (n1) to air (n2) since it's going from solid to air. Then I transposed for the unknown n1. Is the approach still okay as I got the same answer? Also,why was the second medium(air) used as n1 in the video?

[@pravintiwari8777]

Hello sir your videos are very helpful csn plz help me out to find the sin inverse of angles bcoz in examination they won't provide calculator ....plz sir help me out 🙏🙏

[@lusekelomunthali8717]

well explained 💯
