1.	Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is 5.6 xx 10^(24), calculate the power of this laser.
Answer» SOLUTION :`E = N hv Nh (c)/(lamda) = ((5.6 xx 10^(24)) (6.626 xx 10^(-34) Js) (3.0 xx 10^(8) ms^(-1)))/((337.1 xx 10^(-9) m)) = 3.3 xx 10^(6) J`
