Question

Major help. A .110 nm photon collides with a stationary electron. After the collision, the electron moves forward the the photon recoils backwards. Find the momentum and Kinetic Energy of the electron.

Answer 1

I know momentum will be \[: p=\frac{ h }{ \lambda }\]

Answer 2

@nincompoop do you think you could help me with this?

Answer 3

Basically this is a type of elastic collision.

Answer 4

Okay @wmj259 I figured it out. I kept adding the 1 instead of subtracting it.
