Electromagnetic radiation of wavelength = 0.30m falls on a photocell operating in the saturation mode. The corresponding

Electromagnetic radiation of wavelength λ = 0.30μm falls on a photocell operating in the saturation mode. The corresponding spectral sensitivity of the photocell is J = 4.8 mA/W. Find the yield of photoelectrons, i.e. the number of photoelectrons produced by each incident photon.
