Q.33. A light source emitting three wave length 5000 A, 6000 A and 7000 A has a total power 2 x 10w and a beam diameter 2x 10*m. The power density is distributed equally amongst the three wave length. The beam incident normally on a metallic súrface of area 10-*m and having a work function of 2.0eV. Find the charge emitted per unit area is one second.
