Monochromatic light of frequency `6.0 xx10^(14)` Hz is produced by a laser. The power emitted is `2.0 xx10^(–3)` W.
(a) What is the energy of a photon in the light beam?
(b) How many photons per second, on an average, are emitted by the source?

Monochromatic light of frequency 6.0xx10^(14)Hz is produced by a laser. The power emitted is 2.0xx10^(-3) W. (a). What is the energy of a photon in the light beam? (b) How many photons per second, on an average are emitted by the source?
