A photon with frequency 9.996 x 10^14 Hz strikes a slab of lead and is absorbed without freeing an electron. a) If the frequency of that photon is the threshold frequency for lead, calculate the work function for lead. Express your answer in eV. b) Assume a photon of wavelength 200 nm strikes the lead, freeing an electron. Calculate the maximum kinetic energy (in Joules) of the liberated electron. c) Calculate the de Broglie wavelength of the emitted electron. You...

A photon moving in the +x-direction, scatters off a free stationary electron. The wavelength of the incident photon is 0.0410 nm. After the collision, the electron moves at an angle α below the +x-axis, while the photon moves at an angle θ = 73.3° above the +x-axis. (For the purpose of this exercise, assume that the electron is traveling slow enough that the non-relativistic relationship between momentum and velocity can be used.) (a) What is the angle α (in degrees)?...

In Compton scattering a photon collides with an electron that is initially at rest. (a) Rank the following quantities in order from largest to smallest. If any two quantities are the same, state this. Explain how you made your ranking. (i) The wavelength of an x-ray photon (ii) The change in wavelength of an x-ray photon in Compton scattering when it scatters through an angle of 0° (that is, the photon continues in the same direction as its initial motion)...

Q4D.1 (Requires completion of chapter R9.) If we shine X-rays (which are very high-frequency electromagnetic waves) at a target, both the wave and photon models of electromagnetic radiation predict that the X-rays will be scattered in all directions by the target. The wave model predicts that the scattered X-rays will have the same wave- length as that of the incoming X-rays (since the incoming waves will wiggle the electron at the same frequency, so the scattered waves emitted by the...
