Question

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 $0.6\,\mathring{A}$
• B. Highest peak is of $K_{\alpha}$ line at $0.7\, \mathring{A}$
• 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

Answer 1

Answer: (B)

Peak of $K_{\alpha}$ is greater than peak of $K_{\beta}$ line.
