Monochromatic light of frequency 6.0 xx 10^(14) Hz is produced by a laser. The power emitted is 2 xx 10^(-3) w. The number of photons emitted, on the average, by the sources per second is

Monochromatic light of frequency 6.0xx10^(14)Hz is produced by a laser. The power emitted is 2xx10^(-3)W . The number of photons emitted, on an average, by the source per second is nxx10^(15) where n is an integer. Find the value of n?

Monochromatic light of frequency 6xx10^(14)Hz is produced by a laser. The power emitted is 2xx10^(-3) W. The number of photons emitted per second is ("Given h"=6.63xx10^(-34)Js)
