Question

In a Compton effect experiment, X-ray photons of wavelength 0.22$A^0$ suffer a Compton shift of 0.02$A^0$. The fractional change in the energy of the incident photons is_________

• A. $1/12$
• B. $6/7$
• C. $5/12$
• D. $5/7$

Answer 1

The correct option is A $1/12$

Given, E(initial energy of photon)$=hc/0.22$ (By the formula $E=hc/\left(wavelength\right))$
e(final energy of photon)$=hc/0.24$
Therefore, fractional change in energy of photon$=(E-e)/E=1/12$
