PhysicsLAB: 2004 Form B

An incident gamma ray photon of wavelength 1.400 x 10^-14 meters is scattered off a stationary nucleus. The shift in wavelength of the photon is measured for various scattering angles, and the results are plotted on the graph shown below.

	(a) On the graph, sketch a best-fit curve to the data.

In one of the trials, the photon is scattered at an angle of 120º with its original direction.

	(b) Calculate the wavelength of this photon after it is scattered off the nucleus.

	(c) Calculate the momentum of this scattered photon.

	(d) Calculate the energy that this scattering event imparts to the recoiling nucleus.
