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 ${\mathrm{K}}_{\mathrm{\alpha }}$ line and the other peak is of ${\mathrm{K}}_{\mathrm{\beta }}$ line

• A

  First peak is of ${\mathrm{K}}_{\mathrm{\alpha }}$ line at 0.6 $\stackrel{\mathrm{o}}{\mathrm{A}}$

• B

  second peak is of ${\mathrm{K}}_{\mathrm{\alpha }}$ line at 0.7 $\stackrel{\mathrm{o}}{\mathrm{A}}$

• 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
