Question a student is asked to use the photoelectric effect, Ask an Expert

Academics

Question: A student is asked to use the photoelectric effect to determine the work function and cutoff wavelength for an unknown sample. Being very lazy, however, the student turns in a lab report stating only that: "When I used 1.49 x1015 Hertz light, the stopping potential was 3.82 Volts.

Part A- What answers should the student have found for the work function and cutoff wavelength for the sample?

Please use as much detail as required in answer. Thanks.
