An electromagnetic radiation has an energy of 13.2 keV. Then the radiation belongs to region of

A

Visible light

B

Ultraviolet

C

Infrared

D

X-ray

Text Solution

Verified by Experts

The correct Answer is:
D
E = 13.2 KeV
`E=(hc)/lamdaimplies (6.6 xx10^(-34) xx3xx10^8)/(13.2 xx10^3 xx1.6 xx10^(-19))~~1Å`
It belongs to X – ray.
