Transcript of Compton Effect

Compton Effect
When Rutherford experimented with alpha particles he was able to determine the positive charges in an atom resided in a nucleus.
Compton experimented with sending x rays instead. Since they move at the speed of light any energy lost to a collision can't slow them down. But they still do loose energy, which translates to a change in wavelength.
Energy is always lost, so the wavelength always increases.
the wavelength shift depends on the mass of the electron and the angle the photon leaves the collision.
As the photon comes in it will collide with an electron (or proton) and cause both to defect out.
An X-ray with wavelength .25 nm is deflected of an electron in a material. If the outgoing ray is produced at an angle of 75 degrees from the incoming ray, what is the new wavelength?
How much energy was transferred to the electron?
How fast would this make the electron move?
