$X-$rays are in nature similar to

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

In vacuum,an electron of energy $10 \ keV$ hits a tungsten target. The emitted radiation will be:

At the time of a total solar eclipse,the spectrum of solar radiation would be:

$X$-rays of wavelength $22 \, pm$ are scattered from a carbon target at an angle of $85^{\circ}$ to the incident beam. The Compton shift for $X$-rays is ......... $pm$.

The ratio of the energy of $X$-rays with a wavelength of $1 \ \mathring A$ to the energy of visible light with a wavelength of $5000 \ \mathring A$ is:
