The frequency and intensity of a light source are both doubled. Consider the following statements. (A) The saturation photocurrent remains almost the same. (B) The maximum kinetic energy of the photoelectrons is doubled.

A

Both (i) and (ii) are true

B

(i) is true but (ii) is false

C

(i) is flase but (ii) is true

D

both (i) and (ii) are false

Text Solution

Verified by Experts

The correct Answer is:
B
Since frequency of light solurce is double, the energy carried by each photon will be doubled. Hence intensity will be doubled even if number of photons remains constant. Hence saturation current is constant. Since frequency is doubled, maximum `KE` increases but it is not doubled.

When light of sufficiently high frequency is incident on a metallic surface, electrons are emitted from the metallic surface. This phenomenon is called photoelectric emission. Kinetic energy of the emitted photoelectrons depends on the wavelength of incident light and is independent of the intensity of light. Number of emitted photoelectrons depends on intensity. (hv-phi) is the maximum kinetic energy of emitted photoelectron (where phi is the work function of metallic surface). Reverse effect of photo emission produces X-ray.
