A photo cell is illuminated by a small bright source placed 1m away When the same source of light is placed 2m away, the electrons emitted by photo cathode

`1//8`

`1//16`

`1//2`

`1//4`

Text Solution

Verified by Experts

The correct Answer is:

Intensity `prop "1/(distance)"^2` , No, of photoelectrons emitted is proportional to intensity of incident light
