Critical Angle Formula

[@benjaminwalker-cox9181]

This changed my life fam I was on the road to destruction and so was my physics folder

[@chrisyu6733]

absolutely useful ,explanation is much better than my teacher !

[@Isaac-ue7td]

This video really help, especially because I basically managed to avoid doing any form of geometry and trigonometry, except for maybe x and y graphs, through middle school and early highschool. This really helped me to sort of catch up.

[@mrbezos4932]

Thank you so much for this video. It finally helped me understand critical angle, I'm definitely gonna revisit before my exams.

[@thomasski_7]

Hey bro, can you help me? What is the critical angle of light traveling from diamond to quartz?

[@donny6826]

Thanks for explaining this, this was surprisingly easy to follow

[@euphoric1361]

Thanks this video helped me a lot in learning British accent

[@thunderbolt2107]

bro why are there vids more helpful than the books i am suppose to study

[@ranasikender823]

Thanks for explaining in wonderful way

[@ayeshaperera.5139]

Loved the video. Amazing work. Keep it up

[@CarlosGomez-fh8oe]

Great video, you saved my exam!!😊😉

[@mdhimelkhan5466]

This calculation was so much helpful for me
Thank you so much 🥰

[@someshfengade9623]

how to find a critical anhle when the refractive indices of air and glass is given plz answer it fast.

[@marissa954]

u should use the refractive index for the incident ray medium..if the light travels from air to water, then use the refractive index of air

[@sagarmaharana7916]

Thank you so much it is good protidure to find critical angle very quickly and time also peace.

[@Biddable880]

Sir, thank you so much.

[@Happy123]

Great explanation, saved my time researching online

[@josiahsikaonga5453]

thank you very much for explaining this it is simple

[@elishachan3254]

a very clear explanation. thank u so much.

[@N1G_HT]

can you please upload again mate

[@leioura]

Thanks for the amazing help!

[@worldforeverything5338]

Thank you very very much.....it really helped me

[@KHK360]

Very well explained sir. This helped me to understand and help my kid also.

I wish we've been allowed the access of calculator...
But we are only allowed to use logbook 😅

[@neetupandey7020]

Tq sir , u explain very well

[@willyj181]

Thanks! For a moment, I thought I was done for

[@karshanpillay5775]

So if you going from 2 different kinds of glass. You can't use this formula right ?

[@voidalot883]

if they have a different index of refraction(n) you can

[@Nathan.22]

Thank you so much

[@ciannawilliams3745]

This really help me

[@osamaalmonjed3913]

thanks, great explanation.

[@salmankhurshid5822]

Thanks alot Sir

[@somyaprasadsahoo7073]

If given to find the refractance index of liquid for which the critical angle is 45 degree
then what would be answer plzz help

[@avasaramchandrasekhar7544]

What to do if the rarer is other than air...........does the formula changes ..

[@avasaramchandrasekhar7544]

Reply please as fast as possible

[@keshav1729]

No man, it's a formula for rarer and denser media not for air.
The formula never changes

[@ryan5797]

@@keshav1729 Actually I believe it would slightly - your index would no longer be 1 for the air it would be whatever your new medium is.

[@hrishikeshsukhtankar6373]

Thanks Sir.

[@zakiayounas1825]

Thanks pal

[@souvlakiwizard1419]

Thx man

[@shreyagowdaabuddingdoctor7898]

Thanks

[@craigcraig3791]

Which calculator is that

[@happylifeindiafirst4580]

How Nr,=1 ?

[@ericsindhuatmadja9837]

question:
another formula to find critical angle is
c=sin^-1(n2/n1)
but didn't snell's law state that n2/n1 = n ?????
could you explain the relationship between the 2 formulas?

[@tomdemandt3632]

I love you

[@Iambram]

thanks
