Solution

The correct option is B K-beta X-rays
When an electron falls from the L shell to the K shell, the X-ray emitted is called a K-alpha X-ray. Similarly, when an electron falls from the M shell to the K shell, the X-ray emitted is called a K-beta X-ray.

Q. Which of the following are electromagnetic waves?
(a) α-rays

Continuous X -rays are made to strike a tissue paper soaked with polluted water. The incoming X-rays excite the atoms of the sample by knocking out the electrons from the inner shells. Characteristic X-rays are subsequently emitted. The emitted X-rays are analysed and the intensity is plotted against the wavelength figure. Assuming that only $K_{α}$ intensities are detected, list the elements present in the sample from the plot. Use Moseley's equation
