Question

The value of Compton wavelength of electron is

• A. $0.0243$ $A^0$
• B. $0.243$$A^0$
• C. $2.43$$A^0$
• D. $24.3$$A^0$

Answer 1

Answer: (A)

$0.0243$ $A^0$

The quantity $\left(\frac{h}{m_{0}c}\right)$ is known as the Compton wavelength of the electron; it is equal to $2.43\times {10}^{-12}$ $m$ or $0.0243A$.

Here, $m_0$ is the ,electron rest mass.
