In a photon- particle collision (such as photon-electron collision), which of the following may not be conserved?
A
Total energy
B
Number of photons
C
Total momentum
D
Both (1) and (2)
Answer
Number of photons
Explanation
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-pa4rticle collision. The photon may be absorbed or a new photon may be crated.
