Question 12 (12 points): In a photoelectric effect experiment you illuminate a metal with light of wavelength 340 nm and measure a stopping potential of 1.38 V. (a) What is the work function of the metal, in electron volts? (b) What is the threshold frequency (or cut-off frequency) of the metal (emitter)? (e) Find the maximum velocity (v) of photo-electrons ejected from this photoelectrode (emitter), Solution:
