Question

How does the stopping potential applied to a photo-cell change, if the distance between the light source and the cathode of the cell is doubled ????

Answer 1

I hope this will help uh

Answer 2

Hi friend !!

Here's ur ans :-

• There will not be any change in stopping potential as it does not depend on the intensity of falling radiation but it depends only on the frequency of radiation.

As we take the source far away the intensity alone changes and not the frequency of radiaion.
