A light detector has an absorbing area of 2.00 x 10 -6 m 2? and absorbs 50%
Question:
A light detector has an absorbing area of 2.00 x 10-6 m2?and absorbs 50% of the incident light, which is at wavelength 600nm. The detector faces an isotropic source, 12.0 m from the source. The energy E emitted by the source versus time r is given in Figure 38-24 (Es?= 7.2nJ, ts = 2.0s). At what rate ate photons absorbed by the detector?
