Photons of wavelength lamda emitted by a source of power P incident on a photo cell. If the current produced in the cell is I, then the percentage of incident photons which produce current in the photo cell is. (where, h is Planck's constant and c is the speed of light in vacuum)

A 100 W point source emits monochromatic light of wavelength 6000 A Q. 1.5 mW of 4000A light is directed at a photoelectric cell If 0.10 per cent of the incident photons produce photoelectrons, find current is the cell. [Given h=6.6xx10^(-34)Js , c=3xx10^(8)ms^(-1) and e=1.6xx10^(-19)C ]
