Monochromatic light of frequency `6 xx 10^(14)`Hz is produced by a laser. The power emitted is `2.0 xx 10^(-3) W`. How many photons per second on an average are emitted by the source ?

Monochromatic light frequency 5.0xx10^(14) Hz is produced by a laser.The power emitted is 66 W. How many photons per second,on an average ,are emitted by the source?

(i) Monochromatic 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 radiation on a given photosensitive surface.
