4.7 Work function, kinetic energy, and current in a photoelectric sensor. A photo-electric sensor with unknown cathode material is subjected to experimental evaluation. The current in the sensor (see Figure 4.19) is measured while the wavelength of the radiation is recorded. Emission is observed starting with red light at 820 nm. The power density of the incoming radiation is kept constant at 5 mW/cm².a. Calculate the work function of the cathode.b. If the photoelectric sensor is now illuminated
