2. What is the wavelength of a beam of ultraviolet light if its photon energy is 10 eV? If the beam produces photoelectrons from iron, which has a work function of 4.72 eV, what is the maximum energy and the maximum velocity of the electrons?
1. Number of photons that enter the eye per second = 2000/0.02 = 10^4 per ...
This solution provide calculations for finding the number of photons, wavelength, maximum energy, and maximum velocity.
