Question

What happens to the energy of the electron when it absorbs a photon?
A. There is no change in the energy of the electron.
B. The energy of the electron increases.
C. The energy of the electron decreases.
D. The energy of the electron constantly varies.

Answer 1

The answer is b. Electron increases

Answer 2

The energy of the electron increases when it absorbs a photon, therefore the correct answer is option B

What is the photoelectric effect?

It is the process by which a substance releases electrons as a result of absorbing electromagnetic radiation in the form of photons from light waves.

Due to the fact that light functions as particles when it contacts a metal surface, the photoelectric effect causes electrons to be knocked off the surface, creating an electric current.

When light strikes a metal surface, electrons are released, and this is known as the photoelectric effect. It was predicted that the number of released electrons would depend on the light wave's frequency and that the kinetic energy of those electrons would depend on the light wave's intensity.

Thus, The energy of the electron increases when it absorbs a photon, therefore the correct answer is option B
