Given below are some famous numbers associated with electromagnetic radiations in different contexts in physics. State the part of the electromagnetic spectrum to which each belongs.
14.4 keV [energy of a particular transition in `""^(57)Fe` nucleus associated with a famous high resolution spectroscopic method (Mossbauer spectroscopy)].

Explanation

From E = hv,
`therefore v=(E )/(h)=(14.4xx1.6xx10^(-16))/(6.6xx10^(-34))`
`v=3.49xx10^(18)~~3.5xx10^(18)Hz`
Above radiation is at the end of section of X - rays or in the beginning of section of `gamma` - rays.
