7. (a) If the average frequency emitted by 200 W light bulb is 5.00E14 Hz and 10.0% of the input power is emitted as visible light, approx how many visible light photons are emitted per second? (b) At what distance would this correspond to 1.00E11 visible light photons per square centimetre per second if the light is emitted uniformly in all directions?
