Asodium lamp emits light at the power p = 70.0 w and at the wavelength λ = 600 nm, and the emission is uniformly in all directions.
(a) at what rate are photons emitted by the lamp?
(b) at what distance from the lamp will a totally absorbing screen absorb photons at the rate of 1.00 photon /cm2s?
(c) what is the rate per square meter at which photons are intercepted by a screen at a distance of 1.90 m from the lamp?
