Given that a photon of light of wavelength 10,000Å has an energy equl to 1.23eV. When light of wavelength 5000Å and intensity I0 falls on a photoelectric cell and the saturation current is 0.40×10⁻6 ampere and the stopping potential is 1.36 volt, then
(i)What is the work function?
(ii) If intensity of light is made 4I0, what should be the saturation current and stopping potential?
