Question : 7
Total: 27
A photon and a proton have the same de-Broglie wavelength λ . Prove that the energy of the photon is ( 2 m λ c ∕ h ) times the kinetic energy of the proton.
Solution:
For writing expression for energy of photon
For writing expression for kinetic energy of proton
For proving the relationship between the two
Energy of photon,E p =
For proton,λ =
m v =
Kinetic energy of proton,
E k =
m v 2
E k =
E p = (
) E k
