Problem 5.277

Electromagnetic radiation of wavelength \(\lambda=0.30 \mu \mathrm{m}\) falls on a photocell operating in the saturation mode. The corresponding spectral sensitivity of the photocell is \(J=4.8 \mathrm{~mA} / \mathrm{W}\). Find the yield of photoelectrons, i.e. the number of photoelectrons produced by each incident photon.
