Question: As the intensity of incident light increases [CPMT 1999; CBSE PMT 1999; MH CET (Med.) 2000; KCET (Engg./Med.) 2001; Pb. PET 2001]

Options:

A) Photoelectric current increases

B) Photoelectric current decreases

C) Kinetic energy of emitted photoelectrons increases

D) Kinetic energy of emitted photoelectrons decreases

Show Answer

Answer:

Correct Answer: A

Solution:

Intensity increases means more photons of same energy will emit more electrons of same energy, hence only photoelectric current increases.
