For some reason (most likely lack of coffee and sleep), I can't figure out these questions. I assume they all have to do with conservation of energy and/or momentum, but I'm lame and need help.
Explain clearly why the following processes are impossible.
1) A single photon strikes a stationary electron and gives up all its energy to the electron.
2)A single photon in free space is transformed into an electron and a positron.
3) A fast positron and a stationary electron annihilate, producing only one photon.
I also have a million other questions, but I'll keep my first post short.
