A light detector has an absorbing area of 4 0 x 106 m and absorbs 40 of the incident light which is at wavelength 500 nm The detector faces an isotropic source 10 m from the source The energy E emitted by the source versus time t is given in the figure here E 7 8 nJ t 2 5 s At what rate are photons absorbed by the detector E nJ E 0 N s 1 v
