Many teachers camee but still on 20 Feb 2023 I am here to watch Alakh sirr..... Fabulous Explanation....👏 Thank you so much sirr.. A GREAT RESPECT FOR YOU 😌
U have really taken all my tensions of physics.... U are Like a Magician 👼👼👼👼👼who has come from heaven to solve the problems of my most difficult and hated subject .... Physics... Now I like to study physics.... Just because of you...
I just started watching the video and after watching it for 4 minutes I am writing this comment . I got soooo much impressed by this real world superhero . Love you soo much sir ☺️☺️
12:42 I think the reason is that... of a given light if its speed is more in a given medium (other than air/vaccum) its wavelength is more that is why violent is bend more than that of red since red travels more fastly than violet in glass....MAYBE..Please reply wheather it is correct or wrong
DEAR SIR, AT 7:55, THE ANGLE (SUPPLEMENTARY) TO THE ANGLE BETWEEN THE EMERGENT RAY AND THE PRODUCED INCIDENT RAY SHOULD BE THE ANGLE OF DEVIATION IF I AM WRONG PLEASE PARDON ME
I used to learn from him in class 11 th and today i m in last year of my graduation nd i have to do experiment of dispersive power jo just came here revise all those small points for the initial viva for thr experiment !
Sir u said that a ray of light when passes through a prism then the ray refracts towards its base. What will happen when the prism is a HOLLOW prism? Sir plsssssss plssss plsss answer.
Sir you are the best. I’ve watched so many other people’s videos on physics but no one is as fine as you sir. Thank you so much for making such beautiful videos with so much of patience and enthusiasm. And your explanation is spot on. May god bless you.😊🙏🏻
"Without darkness there can no star shine Life is not just a minute' s time You became the darkness of my life To make me the brightest star tonight " _- to the best teacher (Alakh sir)
I just love ur videos plz sir donot stop making our doubt clear thankyou sir....love u somuch Hamare teacher kya padhate hai kich samajnahi aata bass aapke video dekhta hu tension khatam,😍😍😍😍😍love u sir
Sir,you said that we cannot explain how the angle of prism affects the refractive index but i'd like to think about it this way as you can imagine that if we increase the angle of prism,clearly both of it's refracting surfaces get far from each other so,it can be related to the thickness of prism. The more the thickness of prism,the more the time light takes to cross the prism and thus,suffers greater refraction because it speed decreases more to what it had decreased if it would pass through a thin prism with less angle of prism because I think that refractive index is also the extent if slowing down of light in a medium. I am not sure about it. Please ignore if you think that this is ridiculous or correct me if you know the right thing
@@star-fm8pe but yet,to make it clear,its clear when I say that refractive index depends on angle of prism that a prism with variable optical density is being referred to which(hypothetically),should lower the angle of deviation if the angle of prism is made arbitrarily close to zero and vice versa(presumably). But hey,that's just a hypothesis made by my stupid self more than an year ago based on several books,you don't need to take it seriously.
THANKS SIR, aj aapna bachadiya, ab toh is chapter sa koi bhi question ayega hum toh zaror kar payange, sir aj selections hai, again a very big THANKS 2 U SIR

It is the angle btw incident ray produced forward and the emergent ray produced backward is called angle of deviation
