- 0.048 Å
- 0.024 Å
- 0.48 Å
- 0.24 Å
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Using the Compton shift formula:
\[ \Delta \lambda = \frac{h}{m_e c} (1 - \cos \theta) \] For backscattering (\(\theta = 180^\circ\)), we get:
\[ \Delta \lambda = 0.024 \text{ Å}. \]
\[ \Delta \lambda = \frac{h}{m_e c} (1 - \cos \theta) \] For backscattering (\(\theta = 180^\circ\)), we get:
\[ \Delta \lambda = 0.024 \text{ Å}. \]
