Question
The quantum nature of light explains the observations on photoelectric effect as ______.
Options
there is a minimum frequency of incident radiation below which no electrons are emitted.
the maximum kinetic energy of photoelectrons depends only on the frequency of incident radiation.
when the metal surface is illuminated, electrons are ejected from the surface after sometime.
the photoelectric current is independent of the intensity of incident radiation.
Solution
The quantum nature of light explains the observations on photoelectric effect as there is a minimum frequency of incident radiation below which no electrons are emitted.
Explanation:
The photoelectric effect is explained by the quantum nature of light, which states that electrons are not emitted at frequencies below a certain threshold. The minimum frequency is known as the threshold frequency.
