Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosenstive surface.

(i) Mono chromatic light of frequency 6.0xx10^(14)Hz is produced by a laser. The power emitted is 2.0xx10^(-3)W . Estimate the number of photons emitted per second on an average by the source. (ii) Draw a plot showing the variation of photoelectric current versus the intensity of incident radiation on a given photosensitive surface.

How does the photoelectric current vary with the intensity of incident radiation?

In a photoelectric experiment increasing the intensity of incident light

How will the photoelectric current change on decreasing the wavelength of incident radiation for a given photo-sensitive material?
