Описание: A photocell is operating in saturation mode with a photocurrent 4.8 mA when a monochromatic radiation of wavelength 3000 Åand power of 1wM is incident. When another monochromatic radiation of wavelength 1650 Å and power 5wM is indcident, it is observed that maximum velocity of photoelectron increases to two times. Assuming efficiencyof photoelectron generation per incident photon to be same for both the cases, calculate.(a) the threshold wavelength for thecell (b) the saturation current in second case (c ) the efficiency of photoelectron generation per incident photon.
