Question

Consider photoelectric effect. The number of incident photons is the same for all frequencies. The plot that best describes the dependence of the number of photoelectrons (n) emitted as a function of the incident light frequency (ν) is

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is D

In the photoelectric effect, the number of emitted photoelectrons is dependent on the frequency of the incident light. Below a certain threshold frequency, the light does not have enough energy to emit any photoelectrons, leading to a zero number of emitted electrons. Once the threshold frequency is exceeded, the number of emitted photoelectrons increases.

Thus, the correct plot is option (D), which corresponds to the behavior of the photoelectric effect
