Hello Sir, I am a Physics Educator for JEE Mains. NEET and students of class 11th and 12th. One of my students had also once asked this question from me. I am SO happy to see you answering science questions like being answered by you. 🙏🙏😄 many thanks!🎉
Sir, you teach in a very precise way. When you teach I understand it perfectly you are the most sensible teacher I know in existence. You are quite wise and totally a perfect teacher. Well, My teacher took out a rabbit from a hat and gave it the same question that you explained to us in this video I could successfully answer it correctly. All credits go to you. I admire your passion for teaching you are an avail teacher. I suggested my friends your channel and they were shocked to find such a good teacher all thanks to you
Love you sir,I am reading Feynman Lectures on Physics Volume 2 and your book on Electromagnetism and I'm enjoying the beauty of it at every step.Thanks for writing such a delightful book
@Moonlight Gamers ook Edit : I said that coz I learnt a few concepts of class 12th while I was in 9th coz of curiosity and I did understand a lot...so I thought....
If I get a reply from you Sir, my life will be meaningful. I'm an English teacher but I come to your channel from time to time because Physics has been my true love. I was never guided properly to pursue the subject; thank you for motivating me to learn again. 🙂

@@pranavpratik. You see, moon is revolving around the Earth, which creates a centrifugal force, which opposes the Earth's gravitational force. The effect of the gravitational force of Earth is cancelled out by the centrifugal force which is why the moon does not fall into the Earth.
@@pranavpratik. Your question is really good. As another commenter said, it's because of the centrifugal force. Don't worry if you don't understand it right now. It is a part of your syllabus in 11th grade. You'll be taught it there =)
Awesome sir ji...Though i m mechanical engineer graduate...but i have love toward physics and its phenomena ..and feel great interest in watching your videos...though not regularly watch...and highly respect your physics knowledge..!!
I do not understand well semiconductor in class but after reading your book my maximum doubts solved easily and also my knowlegde increases .... Thank you sir for this beautiful book , I have solved main exercise of your book for jee mains exam ...💖💖❤💖❤❤💖💖❤💖❤💖💖❤❤💖💖❤
Sir you're living legend! Your books and lectures drive me towards physics.. you really give me a new perspective to Physics...thank you sir.. Thank you for being with us sir
Answer is : intensity of Scattering is inversely proportional to 4th power of wavelength, is only 1 criteria , the other is particle size , the particles which scatters the light of perticular color must be of size slightly smaller than wavelength of light, the particle size is greater than wavelength of violet and indigo and slightly smaller than blue
In spite of having outstanding knowledge in his own field,he possesses a meek and bashful facial expression that deserves attraction & respect from the teachers as well as the students community. Hat's off.❤
I know that he is a 10th kid but he should have researched this. It's really easy. I know asking something from the best is good but learning physics by yourself is the best feeling.
Sir, I am a 1st year btech student and have a question on ydse experiment. In one video you explained the formation of dark and bright fringes by single photon interference. In our text books it is mentioned redistribution of energy takes place on screen. So my question is how this redistribution of energy takes place and in which form the energy exists at dark fringes(for example when two wave impulse of opposite phase and equal amplitude in a string when gets superimposed the potential energy becomes zero and kinetic energy becomes equal to total energy).
Hi, I think you need to understand Photon statistics and non-classical behaviour of light to understand the answer to your question which is much beyond the classical realm of YDSE that we know. Since here we are talking about a single photon which is interfering with itself in sort of a superposition in contrast to the classical case in a normal YDSE. If you study optics/photonics further and do not get into the IT sector later in life, maybe you will find an answer :) Good Luck
As per i know, there is no energy in the dark fringes, instead in bright fringe, the energy is doubled (as it adds up the energy of the bright and dark fringe)
This was a good question, since when we are exposed to very strong light or simply, sunlight for a long time, after looking away, we do see glimpses of indigo and violet flash before our eyes for milliseconds.
Thank you sir 🙏 for solving my doubt it was my doubt and asked it by many more but i was not satisfied and after watching this video my doubt was finally solved
Sir you should write a book on general physics that we use everyday like Prof Walter Lewin and Neil deGrasse Tyson wrote...I mean like that....some books for general reader......I think it will be phenomenal book for us 😊😊
Sir, I am an average student and I didn't like physics. I think it was so hard but when I started my studying book it was easy for me. Thank you sir your words give me inspiration and motive to do hard work.
@@primenumberbuster404 Mene to apni preparation tabhi start krdi thi jab mai 1 month ka tha...log demotivate krte the ki it's too late now.. But i kept hustling and believed in myself. Now I am in IIT Mars.
I love watching your videos sir...i am in 9 th class now and i am studying physics from your book and yesterday i came across a chapter which we all know Newton's Laws Of Motion in which there is a relation between force and momentum that force is directly propotional to rate of change of momentum.My question is that" how and why force is directly propotional to rate of change of momentum ".please sir can you make a conceptual video on this topic.
You know that P(momentum) = mv, F= ma, and rate of change of velocity is acceleration (these are basics you should know) [[[[Also please remember that rate of change (with respect to time) can be expressed mathematically by differentiation(formulated by Newton and one other scientist)]]]] We can write Rate of change of momentum = mass(mass doesn't change, *generally*) × rate of change of velocity Rate of change of momentum = mass × acceleration = Force So we get rate of change of momentum is equal to Force and thus if momentum is increased Force increases. Sir will definitely never make a video on this since it can't be explained conceptually but only by maths, it can only be visualized if you have a good teacher teaching you this. Comment if you couldn't comprehend one specific part Remember that momentum is a defined term which means we gave meaning to it (a good teacher will explain you how we got these physical quantities by doing different long derivations and getting same repetitive terms). Don't mind what I just told you'll most probably understand when you hit class 11.
In very superficial terms, If 'A' is directly proportional to 'B'; then when the quantity of 'A' is increased, the quantity of 'B' also increases. Similarly, If the external force on an object increases, its velocity increases. Momentum(P)= Mass(m)*Velocity(v) Therefore, Change in momentum= mass* acceleration.......(since, mass is constant) Force= mass*acceleration :D

Sir we say that blue colour scatters in sky during day afternoon, that's why we see blue colour of sky, and when we talk about red colour of the sky in morning or evening, we say it scatters least that's why we are able to see, I am confused in the fact that should the colour be scattered or not to see the sky?
Basically sir, violet scatters the most during only one portion of the day, to be precise on noon. Here the light has to travel the least, and hence it reaches to eyes with minimal scattering. Blue sky when light has to travel medium distance whereas for Red sky when the light has to pass through a greater distance to reach our eyes.
I asked this same question when I was in 12th and my physics had a smile on his face and he asked "kaha se tumko ye baat dimag me aaya"? I was very surprised that if I asked something wrong but sir answered it and gave me a applause
I am so happy because after 2 months of studying the chapter: human eye and colourfull world, I just let know about the intensity of blue and violet huhh thanksssss sir again and also no other channels had explained this clearly than you
My argument is that. It is possible that all the Indigo or violet light already scattered high in the sky so what we see is the colour which is scattered later on. That is blue, and according to this argument the sky should appear blue if we go high enough and we have seen that this is true as in skydiving videos.
Way back in school 15years ago..I too had the same question in mind but obviously no class teacher knows about it and he was not on TH-cam so I never got this answer. But finally I got it. Thank you sir😊

Hello sir,
Sir,I'm class 12th student I have a question:
Sir, as per plank's theory E=nhv
So, energy is inversely proportional to wavelength
Intensity =energy /time area
So, intensity directly proportional to energy and inversely proportional to wavelength. But when we read in spectral lines e.g balmer series we say in transition from n=3 to n=2 intensity of radiation is maximum but shouldn't it be mini in that case bcoz there wavelength of emited energy is maximum.
I have this question in my mind when i was in class 10th.

here are two factors affecting color of sky
