Question

A energy of an electromagnetic radiation is 13.2keV this radiation is related to which region of spectrum

Answer 1

Answer is X-Rays

Explanation:

As we already know that Energy of electromagnetic radiation depends upon the frquency of radiation.
Enrgy of a photon of EM radiation with frequencyis E=hf
frequency and wave length are related by λf=C
E=hf=hc/λ
λ=hc/E
=1240ev-nm/13.2kev
=1240ev-nm/13.2 x1000ev
=1240/13200=0.093nm
=0.093 nm
As X ray wavelength is in the Range of 0.01nm to 1nm .
Hence answer is Xrays.
