Whenever a stream of electrons collides with a stream of photons, in this collision, which of the following is not conserved?

Options

  1. ALinear momentum
  2. BTotal energy
  3. CNo. of photons
  4. DNo. of electrons

Correct answer

C. No. of photons

Step-by-step solution

In a photon-particle collision (such as photon-electron), the total energy and total momentum are conserved. However, the number of photons may not be conserved in a collision. The photon may be absorbed or a new photon may be created.
