A) intensity of incident beam
B) frequency of incident beam
C) velocity of incident beam
D) work function of photocathode
Correct Answer: A
Solution :
The phenomenon of emission of electrons from metals under the effect of light rays is called photoelectric effect. The electrons emitted by photoelectric effect are called photoelectrons and the current produced is called photoelectric current. The photoelectric current or the rate of emission of photoelectrons is directly proportional to the intensity of incident light.You need to login to perform this action.
