I had so much difficulties to understanding Diffraction and interference, but your was very helpful. Thank you!😬

[@physics1663]

You're Savior of students on the night before exam😂😂😂but nice video....... thanx

fact...

[@eldadecimus3404]

oh thank you after watching 3 *15 minutes videos finally gets to your 4 minutes video that i understand what constructive and desct interf is without even finish watching it clear simple and cut to the chase really hope you continue to make videos like such

[@irenelin524]

Thank you so much for making this video!!! I really love the comparisons that they help a lot to clarify the concepts!

Hello 👋

[@bhattkrishna007]

Where are you from

[@zaspanyflegmatyk2446]

JESUS CHRIST THANK YOU DUDE that video was great srsly those 4 minutes were better than a whole lesson

[@RumoHasIt]

I wish this had been around last semester when I was trying to understand the patterns waves would make on screen. Very helpfull as a refresher though, thankyou!

[@mikaelahough6909]

just learnt two months worth of material that my teacher couldn't teach in 4 minutes. Thank you

[@BensChemVideos]

You're very welcome! Many thanks for watching and commenting 😀

Thank you from Bangladesh.

[@dr_akshatamali]

u cleared my doubt very well.....thank u v much

[@BensChemVideos]

You're very welcome! Thanks for watching and for your feedback 😀

[@pfeliciano4062]

Amazing video, my physics professor wants us to know this concept, and you taught it well.

[@BensChemVideos]

Thanks dude! 😀

[@BianCatsumi]

Thank you very much for this video! You are very helpful!

god bless u for saving my exams!!

[@HowTo_withSirAulo]

Thanks, short video but clearer explanation. More power to you

[@eliyahomar]

You are unbelievable, Thank you so much for making things so simple to understand

[@BensChemVideos]

Thanks for your kind words, and thanks for watching! 😀

[@syam_editz]

Excellent

[@hamoudalotaibi2278]

short video a lot of information. Thanks man a lot.

[@pakistan010203]

Very nice Informative vedio. Thanks alot buddy.

[@sanchita6113]

Very good explanation

[@sreyasthejas4715]

waves can go through the slit directly , without bending right?

[@sudheerkumarpatnana6369]

nice explanation

[@saraatallah203]

Thank u very much u literally saved my life'😭😭😭💙💙💙💙💙💙

[@sathyareddy7157]

it's very good i have really understood thanks

[@mohdparvez9874]

I really found this helpful!! And thanks!!!

[@abhakumari7220]

Best one

[@sachinrath219]

for diffraction to occure will slit width (a) be smaller,if so d/a ratio will be bigger and diffraction envelope may become flat and only interference will be observed,pl clarify,thanks.

[@rupeshshivgan1571]

thanks dear friend

[@rajgogawale4980]

really good

[@NityaKrishnaDas926]

Thank you so much now I am confident ☺

[@BensChemVideos]

You're very welcome! Glad to hear you're confident! Many thanks for watching and commenting 😀

[@erasmith3511]

Very well explained

[@vinodkumar-wm3oq]

I have two questions - first , can we get that interference with two separate identical sources of light rather than passing light from the same source through the two slits(what exactly is the role of the slits)? We don't see this in regular life when we pass two torches or lasers through each other. Second, how is the energy conserved when the waves interact destructively? Please, reply and clear my doubts.

[@BensChemVideos]

The answer to your first question is yes. I think the reason why we don't see it is because the naked eye is not advanced enough to pick up the interference pattern. We see what appears to be a single glow of light. Have you ever tried experimenting with two lasers in the dark? Perhaps the sunlight is filling in gaps in the interference pattern. Your second question is very interesting, and to be honest, I've never considered that. I suppose that energy of the two photons would be released into the universe in the form of heat, but I'm not 100% sure about that. I'm stumped! Thanks so much for watching!

[@vinodkumar-wm3oq]

Ben's Chem Videos , thanks for replying and clearing my doubt. I was also wondering about my second question and then I thought if we consider the whole interference pattern then the total energy will be constant, because the bright regions have double the brightness then the source of light itself. Almost like we are alternatingly focusing light. I have a lot more questions so I'm gonna ask a few more - first, why does light travel at the same speed from all frams of references? because it really seems unintuitive that light is so fundamental that it even slows down time to make us feel that it is still at light speed. But what about the universe out of the observable universe, why does that seem to be moving away from us faster than the speed of light? Second question(might seem unrelated) - are irrational numbers endless source of entropy? Because I saw some videos explaining how information and randomness are entropy and entropy always increases so information in the universe always increases. I saw some arguments that quantum phenomenon increase the information in the universe but I thought irrational numbers are endless information. So the universe must have endless information. And that's pretty good because it defy's the simulation theory.

u deserve subs

[@anshuldhote1397]

U are excellent thankyou sir

[@computechsy0285]

oh thnx its only a 4:14 but it is useful for us l hope you will make extra videos regarding Ch. 11 of 12 std.

[@baharosman1416]

QUESTION: why then do we say that the rainbow of Cd and dvd is made by diffraction? It’s right they have slit but the slit is closed so shouldn’t it be interference?

[@BensChemVideos]

I think you might be confusing diffraction with refraction.

[@jiniyabanerjee549]

So gud !!!

[@supriyachavan1860]

Nice

[@Ankitakumari-om3rr]

Thank you so much it was very helpful for me 😊😊

[@JonKurichan-cn9yu]

Thank you for saving me from failing science :) its kinda complex

[@BensChemVideos]

You're very welcome! Thank you for watching!

[@prernadumka7701]

That was helpful.

[@michellec.4291]

I get it now! thank you so much

[@radinelaj3932]

I think if that experiment would be replaced with a canon sand( not laser canon) would happen the same thing. It means : the experiment doesn't show anything because sand is particle, that( same thing ) would happen with all things as : sugar grain,salt grain, sand grain etc...( the photon doesn t interfere with itself but crashes with border of slit part (ricocheted the lips/borders of the slit )

For the first time I actually know what these things mean! I mean I read the whole chapter with numericals and derivations and stuff and in the end I was like... What the hell IS interference and diffraction for god's sake!?
