Okay, so here's the problem:
In a Compton scattering experiment, a photon is scattered through an angle of 90.0 and the
electron is set into motion in a direction at an angle of 20.0 to the original direction of the
(a) Explain how this information is sucient to determine uniquely the wavelength of the
(b) Find this wavelength.
λ2 - λ1 = (h/m c)(1 - Cosθ)
The Attempt at a Solution
So, with the angle I'm given I can find Δλ, but I won't be able to find λ2 which is what I believe the question is asking me to find. I feel like I should be using the angle of the electron but I don't really see how I can. Can anyone help me out here? :S
