Question: A light detector (your eye) has an area of 2.00 x 10-6 m2 and absorbs 80% of the incident light, which is at wavelength 500

A light detector (your eye) has an area of 2.00 x 10-6 m2 and absorbs 80% of the incident light, which is at wavelength 500 nm. The detector faces an isotropic source, 3.00 m from the source. If the detector absorbs photons at the rate of exactly 4.000s-1 at what power does the emitter emit light?
