in a photo electric setup, a point source of light of power 3.3*10^-3W emits mono energetic photons of energy 4.5eV. the source is located at a distance of 750mm from the center of a stationary metallic sphere of work function 3.1eV and of radius 7.8cm. the efficiency of photo electron emission is one foe ever 10^5 incident photons. assume that the sphere is isolated and initially neutral and that photo electrons are instantly swept away after emission. calculate the number of photo electrons emitted per second
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
