(b) A sodium vapor lamp is placed at the center of a large sphere that
absorbs all the light reaching it. The rate at which the lamp emits energy
is 80 W; assume that the emission is entirely at a wavelength of 380 nm.
Evaluate the rate at which the photon is absorbed by the lamp.
Take,
Planck Constant h = 6.63 x 10-34 J.S
Speed of light
c = 3.00 x 108m/s
