Hence electric current
I= Q/Δt or charge/time
= 500/25 = 20 amps
That effect you're describing is called the Zeeman effect.
The Zeeman effect is the splitting of a spectral line into several components in the presence of a static magnetic field. This occurs because the magnetic field interacts with the magnetic moment of the atom's electrons, causing the energy levels of the electrons to split. As a result, the photons emitted or absorbed during transitions between these energy levels have slightly different frequencies, leading to the splitting of the spectral line.
There's a similar phenomenon involving an electric field instead of a magnetic field, which is called the Stark effect.
The reverse effect of X-ray emission is the photoelectric effect.
X-ray Emission: In the process of X-ray emission (specifically the production of continuous X-rays or Bremsstrahlung radiation), high-energy electrons are decelerated when they strike a target material. This deceleration causes them to lose kinetic energy, which is then emitted in the form of X-ray photons.
Photoelectric Effect: In the photoelectric effect, a photon (with sufficient energy, like an X-ray photon) strikes a material and causes the emission of an electron from the surface of that material. The photon's energy is absorbed by the electron, allowing it to overcome the binding energy and be ejected.
The scientist who was awarded the Nobel Prize for his services to Theoretical Physics, and especially for his discovery of the Law of the Photoelectric Effect, is Albert Einstein.
A photocell converts light energy into electrical energy.
Specifically, when light (photons) strikes the photosensitive material in the photocell, it causes electrons to be released, creating an electric current. This is the fundamental principle behind solar panels and other light-detecting devices.
