A metal surface is illuminated by a light of given intensity and frequency to cause photoemission. If the intensity of illumination is reduced to one-fourth of its original value, then the maximum KE of emitted photoelectrons will become.

A

`((1)/(16))`th of original value

B

unchanged

C

twice the original value

D

four times the original value

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum KE depends on the frequency of incident radiation, not on intensity.

Assertion: A photosensitive surface is illuminated by a monochromatic light of wavelength lambda and intensity I. The number of photoelectrons emitted per second is doubled when the intensity of light is doubled. However, the maximum speed of emitted electrons remains unchanged. Reason: The number of electrons emitted per second is directly proportional to the intensity of the incident light. The kinetic energy of the emitted photoelectrons is independent of the intensity of the light.

In photoelectric effect if the intensity of light is doubled then maximum kinetic energy of photoelectrons will become
