When stopping potential is applied in an experiment on photoelectric effect, no photo current is observed. This means that

A

the emission of photoelectrons is stopped

B

the photoelectrons are emitted but are reabsorbed by the emitter metal

C

the photoelectrons are accumulated near the collector plate

D

the photoelectrons are dispersed from the sides of the apparatus.

Text Solution

Verified by Experts

The correct Answer is:
B
Emission of photo electron is independent of external factor.It depends only on the nature of the material and wavelength of incident light
