Question

monochromatic light is placed at distance d from metal surface
photoelectron are ejected at rate of n per sec with max KE if
source is brought nearer to distance d/2 then rate and KE becomes?

Kaustubh Kakade · Answer

The rate of photoelectric emmision and the kinetic energy of
photo-electrons are independent of distance of source, they depend
only on frequency of light Hence, in the second condition, the rate
of photoelctric emmision is n per sec

monochromatic light is placed at distance d from metal surface. photoelectron are ejected at rate of n per sec with max KE. if source is brought nearer to distance d/2 then rate and KE becomes?
