Q.
In a photon-particle collision (such as photonelectron collision), which of the following may not be conserved?
Dual Nature of Radiation and Matter
Solution:
In a photon-particle collision, (such as photon electron collision), the total energy and total momentum are conserved. However, the number of photons may not be conserved in photon-particle collision. The photon may be absorbed or a new photon may be created
