Write short nots on X -rays

Explanation

It is produced when there is a sudden deceleration of high speed electrons at high -atomic number target, and also by electronic transitions among the innermost orbits of atoms. The wavelength range orbits of atoms. The wavelength range `10^(-13)` m to `10^(-8)` m and frequency range are 3`xx 10^(21)` Hz to `1 xx 10^(16)`Hz. X -rays have more penetrating power than ultraviolet radiation. X-rays are used extensively in studying structures of inner atomic electron shells and crystal structures. it is used in detecting fractures, diseased organs, formation of bones and stones, observing the progress of healing bones. further, in a finished metal product,it is used to detect faults , cracks, flaws and holes
