Q. If $\lambda_{1}$ and $\lambda_{2}$ are the wavelengths of characteristic X-rays and gamma rays respectively, then the relation between them is
A) $\lambda_{1} = \frac{1}{\lambda_{2}}$
B) $\lambda_{1} = \lambda_{2}$
C) $\lambda_{1} > \lambda_{2}$
D) $\lambda_{1} < \lambda_{2}$
Explanation
(c) In general $X$-rays have larger wavelength than that of gamma rays
