How can a photon without electric charge interact with the electron with electric charge?
Do you think that the universal ether (ether) exists? Why?

Let me start the discussion about the simplest atom, hydrogen.
It has a radius of 0.5A, ie 0.5E-10m for the electron on the K shell, the first Bohr radius:

The speed of the electron on K is 1/137 of the speed of light.

Now a comparison follows:

What is the wavelength of the radiation that hydrogen absorbs with maximum probability?

Let's understand this graph so: The cross section is the probability expressed in a more sophisticated way. The probability that an electron flux will ionize a hydrogen target. An atom. Depending on the speed of the electrons.

50eV=8E-18J .... V=4.21E6m/s=c/71

You are aware of the interchangeability of mass and energy. An electron has mass and energy, and in a bound atom that energy is quantized. A photon has no mass but is does have energy. Thus the photon can interact with an electron by transferring some of it's energy to the electron. How much energy is transferred? Just enough to raise it to some higher quantize energy level. At some point the electron may feel the pull of the nucleus and drop back down to where it came from. At this point it gives up the energy it acquired from the photon and a new photon is created.

Hello there To reiterate Mr.@Papabravo.
but with a different flavor!
Electrons in an atom or a molecule absorb energy and get excited, they jump from a lower energy level to a higher energy level, and they emit radiation when they come back to their original states. This phenomenon accounts for the emission spectrum through hydrogen too, better known as the hydrogen emission spectrum.
