Given that a photon of light of wavelength 10,000Å has an energy equl to 1.23eV. When light of wavelength 5000Å and intensity `I_(0)` falls on a photoelectric cell and the saturation current is `0.40xx10^(-6)` ampere and the stopping potential is 1.36 volt, then (i)what is the work function? (ii) If intensity of light is made `4I_(0)`, what should be the saturation current and stopping potential?
