Question

Silicon has a photoelectric work function of 7.77 x1019 J per electron ejected from the surface. Answer the following question about the behavior of a silicon surface that has been irradiated with UV radiation with a wavelength of 204 nm. The speed of light c = 2.9979408 ms This question has 4 parts. 1) What is the frequency of the incident radiation? Number 1.4696× 1015 The sig fig rules for addition and subrtraction are different. The answer to part 2 should only contain 2 sig figs. Remember, this precision is then carried into parts 3 and 4
