## Homework Statement

In the Compton Effect, which of the following is conserved? Select all that apply:

- Total relativistic momentum.
- Total energy of the photon.
- Rest mass energy of the electron.
- Total relativistic energy.
- Relativistic kinetic energy of the electron.
- Net charge.

## Homework Equations

Conservation of energy-mass and momentum:

[tex]hv_{i}+m_{e}c^{2}=hv_{f}+\sqrt{(p_e)^{2}c^{2}+(m_{e})^2c^{4}}[/tex]

[tex]pe_i+pf_i=pe_f+pf_f[/tex]

Compton effect:

[tex]\Delta \lambda = \frac{h}{m_{e} c}(1-cos\theta )[/tex]

## The Attempt at a Solution

I think 1 and 4 are definitely correct.

6 seems irrelevant.

I am not sure about the other 3, they seem redundant but can be true.

I chose 1 and 4 and the answer was wrong. I chose 1, 2, 4 and 5 and it was also wrong.
