Question

Explain how photoelectric stopping potential is independent of the intensity but depends upon the frequency of radiation from

Answer 1

U can understand that by their graphs

Or this might help u

Work=potential×charge

Also work = Kinetic energy

So KE= q×V

From this equation we understand if enough energy is given the electrons will have a certain KE and to stop the ejection of electron we have to to do some work =q×V

Here V is stopping potential

So stopping potential is directly proportional to KE amd KE only depends on frequency not intensity

Hope it helps!!
