Question

In photoelectric effect theory, it is assumed that -

• A. multiple photons give all of its energy to a single electron.
• B. one photon gives all of its energy to multiple electrons.
• C. one photon gives all of its energy to a single electron.
• D. None of these

Answer 1

The correct option is C one photon gives all of its energy to a single electron.

In photoelectric effect theory, it is assumed that one photon gives all of its energy to a single electron.

Hence, option $\left(C\right)$ is the correct answer.
