Question

The expression for Compton shift is _________

(a) \(\frac{h}{m_0 c}cos\theta\)

(b) \(\frac{h}{m_0 c}(1 – cos\theta)\)

(c) \(\frac{h}{m_0 c}sin\theta \)

(d) \(\frac{h}{m_0 c}(1 – sin\theta) \)

I got this question during an interview.

My question is based upon X-Rays and Compton Effect in chapter X-Rays and Compton Effect of Engineering Physics II

Answer 1

Right option is (b) \(\frac{h}{m_0 c}(1 – cos\theta)\)

For explanation: The expression \(\frac{h}{m_0 c}(1 – cos\theta)\) is the expression for the Compton shift. It gives the expression for the change in wavelength that occurs during Compton effect.
