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 th egraph one peak is of `K_(alpha)` line and the other peak is of `K_(beta)` line

Options

A. First peak is of `K_(alpha)` line at `0.6 Å`
B. Highest peak is of `K_(alpha)` line at `0.7 Å`
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

B

Explanation

Peak of `K_(alpha)` is greater than peak of `K_(beta)` line.
