Thank you vanhees71 for your explanation but you see I am in high school I don't understand the things you quoted above. I think I can understand it If you could give any example. Classical Physics is Intuitive and just tell me how electron behave when applied AC to a conductor. Also I think...

by electrons rushing I meant they along with thermal motion are having a drift velocity. I am just asking about the visualization of AC. Also I was talking of pure AC as that is what is taught to us. If that SHM thing is wrong then how to think about AC microscopically?

Hello, I was being taught AC in High School, It was good but the way they taught us DC, things like drift velocity, no of electrons per unit volume etc, it was easy to visualize electrons rushing in a conductor. I tried to visualise AC(which was not taught to us) and I came to a conclusion...

Yes, that's my point @lightarrow

Hello, I was just reading optics and I thought that if photon doesn't has mass it can't be accelerated.. If it is so then how it gets reflected off a smooth surface, why don't it just passes from the plane. As any reaction force by the plane couldn't accelerate it , it mustn't rebond as...

Hello everybody, I can't remember the article in which it was written but I just read relativity in people's physics book by ck12 organization it has a question in Relativity chapter-"What would be the Lorentz gamma factor γ for a spaceship traveling at the speed of light c? If you were in this...

I can't get it I am not talking what is behind them rather I am talking about the sideways. Photon's perspective of the universe must be planar so why it is point sized?

So we cannot apply lorentz transformation to photons? Then how we say that it's perception of universe is of a point sized universe?

Hello, I recently read about a photon's point of view according to relativity(which is a fascinating thing for a high school boy), It said to photon's perspective the universe is point sized. But recently I learned that lorentz contraction occurs in the dimension in which the object is...

Actually my question in short language is that why by moving the copper strip the force on the electron vanishes? Despite the field transformation? There should also be a new electric force so as to maintain the Hall potential.

Hello, I was taught that moving charges in an external magnetic field experience force. Okay. I wondered that if the observer was moving with the same velocity as the charge is what would happen? I studied in one book about field transformation and came to know that the charge will...

So the thing tiny-tim said was wrong? It sounded quite convincing...

So you are saying current is a scalar , tiny-tim is saying its a vector! So what actually is the answer and describe me the tensor thing also please. Thanks

Thanks tiny tim for a quick reply but why there is such a paradox in all the books. The water's momentum analogy is a special case, seeing this case one cannot say the momentum is scalar, we have taught from starting that momentum is vector then why current is said scalar in halliday resnick for...

Hello, I am a 15 year old high school student, We were being taught about current, My teacher said its a scalar quantity, I had a doubt on that that since wires bound the charges, we shouldn't say that since wire's orientation doesn't change the magnitude of current, its Scalar quantity. For...
