53. As the intensity of incident light increases
[1999]
(a) photoelectric current increases
(b) K. E. of emitted photelectrons increases
(c) photoelectric current decreases
(d) K.E. of emitted photoelectrons decreases
Show Answer
Answer:
Correct Answer: 53.(a)
Solution:
- (a) K.E. of electrons emitted depends upon the frequency of incident rays rather than the intensity. While number of photo electrons emitted depends upon intensity of radiation.
