Answer
$\rightarrow $ The region of electro magnetic spectrum beyond the $UV$ region is called $X-$ ray region.
$\rightarrow $ Range of wave length: $10^{-8}m(10 \ nm)$ to $10^{13}m (10^{-4}\ nm).$
$\rightarrow X-$rays can be generated by bombarding a metal target by high energy electrons.
$\rightarrow X-$rays are used as a diagnostic tool in medicine and as a treatment for certain forms of cancer.
$\rightarrow $ Because $X-$rays damage $($ or destroy $)$ living tissues and organisms, care must be taken to avoid unnecessary or over exposure.
