Dual Nature Of Light Question 303

Question: If intensity of incident light is increased in PEE then which of the following is true [RPET 2001]

Options:

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

Show Answer

Answer:

Correct Answer: B

Solution:

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