Q. In the diagram a graph between the intensity of $X$-rays emitted by a molybdenum target and the wavelength is shown, when electrons of $30\ keV$ are incident on the target. In the graph one peak is of $K_{\alpha}$ line and the other peak is of $K_{\beta}$ line
A) First peak is of $K_{\alpha}$ line at $0.6\ \mathring{\mathrm{A}}$
B) Highest peak is of $K_{\alpha}$ line at $0.7\ \mathring{\mathrm{A}}$
C) If the energy of incident particles is increased, then the peaks will shift towards left
D) If the energy of incident particles is increased, then the peaks will shift towards right
Explanation
(b) Peak of $K_{\alpha}$ in greater than peak of $K_{\beta}$ line
