Question

A photo electric cell is shown in the figure The emitter plate cathode is made of copper o 4 7 eV and emitter is illuminated by a source of monochromatic light of wavelength 200nm Saturation current is observed when potential difference between cathode and anode is 1V and anode at higher potential Range of ammeter is large Take he 1240 ev nm 1 II Cathode Anode 0 5V 1V List I Minimum kinetic energy of photoelectrons reaching the collector is Maximum kinetic energy of photoelectrons reaching the collector is If only S is closed then A I S II R III Q IV S C IT II P III S IV U S S III If wavelength of incident light is decreased no of incident photon same then reading of current as shown by ammeter will IV If number of incident photons increases then reading of current as shown by ammeter will A List II P 2 5 eV Q Remain same R 1 eV S Increase T O U Decrease B I P II T III R IV S D I R II P III Q IV S
