Like.
In the classical model there is radiation. And in the quantum model there is also radiation. So there is a classical reason and a... -

There is no "classical reason" vs. "quantum reason". You are confusing models with reality. Reality is just radiation. The classical...

Which is why the classical view is wrong.

Both cases have a time-varying dipole moment.

bhobba replied to the thread High School Building intuition for waves (& quantum waves).The book for that, IMHO (it covers Fourier analysis and distribution theory, which circumvents difficult questions of convergence, plus...

I think if you want to build intuition for physical waves, it's best to start with the simple cases -- with waves on a rope, waves on...

I would say classical wave (equations) are about propagation. One can distinguish between propagation in time, and propagation along a...

I guess it depends on what information you hope to obtain- a point detector does not cover all positions, but then your location...

Yes.

Sad.
Hmm, Maxwell didn't understand Maxwell's equations? That's rather surprising! -

Really? You think we don’t grasp the question? No, we understand what they are asking. The problem is just that people don’t like the...

Over the years here I've seen tons of threads about that, and I think no one ever grasped what people are actually asking about...

I am not sure which cgs units have that feature. In Gaussian units permittivity and permeability are both dimensionless and speed is not.

bhobba replied to the thread High School What Medium Does Light Travel Through in Space?.For spontaneous emission, the issue is that, according to ordinary QM, the energy levels are stationary and remain the same. The...

There is no time dilation and twin paradox when using Galilean transformation.
