An $X$-ray has a wavelength of $0.010 \mathring{A}$. Its momentum is

The Compton effect is associated with

$X$-rays will travel the minimum distance in which of the following materials?

If a voltage applied to an $X$-ray tube is increased to $1.5$ times, the minimum wavelength $(\lambda_{\min})$ of an $X$-ray continuous spectrum shifts by $\Delta \lambda = 26 \, pm$. The initial voltage applied to the tube is:

The intensity distribution of $X$-rays from two Coolidge tubes operated on different voltages $V_1$ and $V_2$ and using different target materials of atomic numbers $Z_1$ and $Z_2$ is shown in the figure. Which one of the following inequalities is true?

When cathode rays strike a metal target with a high melting point and high atomic number,what is produced?
