A source of light is placed at a distance of 50 cm from a photocell and the stopping potential is found to be . If the distance between the light source and photocell is made 25 cm, the new stopping potential will be
As we discussed in concept
Stopping Potential /Cut-off Potential -
It is defined as the potential necessary to stop any electron from reaching the other side.
-
Stopping potential depends on frequency of light and not on intensity since frequency of light remains constant, stopping potential will remain same.
