If the voltage of an $X$-ray tube is doubled,the intensity of the $X$-rays will be ...... .

In the characteristic $X$-ray spectra of an atom superimposed on a continuous $X$-ray spectrum, identify the peaks $P$ and $Q$ shown in the graph.

In an $X$-ray tube,electrons bombarding the target produce $X$-rays of minimum wavelength $1\; \mathring{A}$. What must be the energy of the bombarding electrons in $eV$?

$X$-rays are produced due to which of the following?

An $X$-ray tube is operating at $50 kV$ and $20 mA$. The target material of the tube has a mass of $1.0 kg$ and specific heat $495 J kg^{-1} {}^\circ C^{-1}$. One percent of the supplied electric power is converted into $X$-rays and the entire remaining energy goes into heating the target. Then:

The essential distinction between $X$-rays and $\gamma$-rays is that:
