Unformatted text preview: ect an electron from a metal M, occurs in the
infrared at λ = 800nm.
a) b) Sketch the photoelectric graph (i.e. Ekinetic vs. ν) for this metal using the given axes. What is the energy of an incident blue photon with λ = 400nm?
Answer: c) What is the kinetic energy of an electron ejected from M by the photon in part b)?
Answer: d) Calculate the de Broglie wavelength for the electron ejected in part c).
Answer: e) 800 nm light corresponds to transition 3à1 in the energy level diagram shown below. What λ
corresponds to the 4à1 transition? Answer:...
