If the power of the light source is increased, what does it implies that the intensity of the light is increased. But does that not imply that the energy of the photons also increases?

    Stopping potential does not depend on the intensity of incident radiation. For a given intensity of radiation, thestopping potential depends on the frequency.

    dear..... actually u r right
  • Dhairya sharma thankyou
    so if intenaity or power will increase then no of incident photon will increase that will emit more no of photoelectron will increases

    Yes I know that no of photons is directly proportional to intensity. But I wanted to know whether energy will increase or not if power increases

    photoelectric effect doesn't depend on power of radiation. it depends on frequency.

    first of all you should know what is power.....power is intensity of radiation per unit area. it shows no of photon per unit area per unit time.

    mam but power can also be written as E/t
