Question

The quantum nature of light explains the observations on photoelectric effect as ______.

पर्याय

• 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.

Answer 1

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.
