An electromagnetic radiation has an energy 14.4keV. To which region of the electromagnetic spectrum it belongs?

A

infrared

B

visible

C

Ultraviolet

D

X-ray

Text Solution

Verified by Experts

The correct Answer is:
D
Given radiation has 14.4 keV energy, so it is within the energy range for X-rays which is between 100eV to 100keV.
The wavelength of given radiation , `lamda = (hc)/(E ) " joule" = (6.64 xx 10^(-34) xx 3 xx 10^(8))/(14.4 xx 10^(3) xx 1.6 xx 10^(-19))` volt
`= 0.86Å`
X-rays have wavelength range between `0.1 Å " to " 1Å`
