Question

vi) What happens to photoelectric current when intensity of incident radiation is increased?
Q.Answer the question ❓​

Answer 1

Explanation:

As the intensity of incident radiation is increased the energy received per unit area of the surface is increased. As the energy is increased the number of photoelectrons is increased which means the photoelectric current increases.

Answer 2

Photoelectric effect is a phenomenon which is based on the idea that electromagnetic radiation is made of a series of particles called photons.When a photon hits an electron on a metal surface,the electron can be emitted.The emitted electrons are called photoelectrons.

(i)On increasing the frequency the saturation currents remains the same as seen in the first figure.

(ii)On increasing the Intensity the saturation current also increases.
