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-rays

Text Solution

Verified by Experts

The correct Answer is:
D
Given: `E = 13.2 keV`
`lamda ("in" Å) = ( hc)/(E (eV)) = (12400)/( 13.2 xx 10 ^(3)) = 0.939 Å~~1 Å.`
X-rays has a Wavelength range of `10^(-8) m ` to `10 ^(-13)m.`
