When Newton solved JEE Advanced question !

Manish Purohit, former #ISRO​ Scientist​ discusses When Newton solved JEE Advanced question !
We know #JEE Advanced is one of the toughest paper on Earth for teenagers searching for College admissions (#IIT).
What if we tell you that a JEE advanced level question was once thrown as a challenge to #Newton too way back in 1695.
How would have he responded?
What is the #philosophy that the #IIT follows while setting the #questions for #JEE #advanced?
Lets find out together.

Second question answer is Sol= light Har time high potential se low potential ke direction pai jati hai Is liye photon A se B pai exponential DK graph ke Jaise Jayegi

[@chiragkshatriya9486]

The curve you are taking about is called the “Brachistochrone Curve” And We can see that light does not bend when entering at 0 angle with the normal. It only bends when entering at some angle made with normal. This can be explained using Huygen’s principle, Maxwell Equation and ‘spin’ terminology of quantum mechanics, Light is electromagnetic wave. By Huygen’s principle we know that each point of that light wave can act as a separate light source. When light enters 0 angled to normal all hit at once but when entering at an angle to normal, the lowest point of the wave enters first then little up part then little up part..... when we draw Huygen’s figure and with the help of little geometry we can recreate many similar waves in denser medium but we will see all are at an different angle to the original wave. Now to know which all this wave is the wave that actually happens we need to solve Maxwell equations. We know that light is made of both electric and magnetic wave. Making two components of both wave, parallel and perpendicular to the surface rarer and denser medium and then solving the Maxwell equations, we will see that parallel components doesn’t change but perpendicular changes because of different value of permittivity and permeability of both medium and then doing vector addition we get the final wave and is the wave that we choose from all waves that we saw in Huygen’s figure. And why Maxwell equation does acts as it does is because of spin of photon. We know that photon has spin so when it enters into denser medium it’s spin changes and the spin changes in such a way that it takes the least time path. So the wave we get is the probability of all the wave with different spin. This is the reason why light ‘photon’ takes the path it takes and why at so particular angle.

[@rajsekhardey4510]

The second question is not well addressed by the masses here, as I see. Photons can be viewed as a particle or matter wave (anyone of the analogies may be used to describe photon in any situation ). Btw, the quantity waving if squared gives the probability density function. Wavelets are generated as the photon crosses the boundary. These wavelets interfere, and the region where interference occurs constructively has the highest probability of finding the photon. In ray optics we consider that the ray passes through that region. So it really appears magical as how the photon decides which path to to take, though if you were to shut up and calculate, you would get to know the behind the scenes of the magic (not truly though). Yes, Huygens' principle also verifies Snell's law with its far simpler mathematics. However I am not confident enough about the validity of his principle with our present day understanding of things. P.S: I just know that there exists something called quantum mechanics.

newton was the most inspirational, influential and genius he discovered Calculus and was in every area of science because of his discoveries and formulae we are asked question on JEE not the other way around.

[@Azazel._.]

Ofcourse there was Leibniz who had controversy with sir Issac newton till his death over who developed calculus. Even though both of em developed it independently. Newton work for calculus can be seen in principia and Opticks. Leibniz used Newton's infinitesimal as main work to develop calculus.

[@everyone2905]

@Pradeep Chaturvedi well both of them discovered calculus at the same time but we use Leibniz version all around the world,my comment was based on the researches and discoveries published in "Principia Mathematica" which was the very essence of science and mathematics.

[@plutoniumisotope205]

@@everyone2905 newton made differentiation and Leibniz intregation

[@apaar13]

Regarding how the photon chooses the least time consuming path or "stationery time path" 1) it should be considered that the frequency of light do not change (modern day observation) and hence it implies that the time should remain constant now light travels through wavefront (Hygen's principle) ie light can travel in all possible paths including the point say B and hence there is no intention of light involved just property of wave

The path will be that which will have increasing dy/dx magnitude as that will result in the increament of maxm speed as a rest time takem will be minimum therefore downwards concavity will be the answe and that purple line is correct bcs line above and below that have less dy/dx mag change as compared to purple line...i hope im correct sir please address am i or not and if not please tell me my mistake...thank you sir for this amazing question❤❤

Answering "How light know the path which take shortest time?" ----- this can be explained by wave nature of light. Wavefronts need to be continuous. At interface of medias one part of wavefront strikes first and remaining part still remains in previous medium. So in order to maintain continuity of wavefront wave travels such that it takes minimum time. Other way---- since nothing can travel faster than light in any media and light travels at its respective ultimate speed in respective medias ,hence it takes FASTEST path not SHORTEST path.

Bro keep moving ahead. (Whom I m telling this😃)but for Information there are very less people which are interested in physics especially in today's world, just bussy in shitty things and in this situation where the people got excited to watch salman khan's films, you are sharing these type of precious knowledge for free and giving your potential,it is absolutely immensely wonderful & I just want to say that keeping moving!✨🌌🌈
