If intensity of incident light is increased in photo electric effect then which of the following is true ?

A

Maximum `K.E.` of ejected electron will increase

B

Work function will remain unchanged

C

Stopping potential will decrease

D

Maximum `K.E.` of ejected electron will decrease

Text Solution

Verified by Experts

The correct Answer is:
B
With the increase in intensity of light photoelectric current increases , but Kinetic energy of ejected electron , stopping potential and work function remains unchanged.
