Final answer:
When photons collide with electrons, there are three possible outcomes: absorption, energy transfer, or reflection.
Step-by-step explanation:
When a photon collides with an electron, several outcomes can occur. Here are three possible outcomes:
- The photon can be absorbed by the electron, causing the electron to gain energy and move to a higher energy level or be ejected from the atom entirely.
- The photon can transfer some of its energy to the electron, causing it to move to a higher energy level within the atom.
- The photon can bounce off the electron, changing direction but not transferring any energy.
