Correct Answer - D
Given: `E = 13.2 keV`
`lambda("in" Å) = (hc)/(E("in"eV)) = (12400)/(13.2 xx 10^(3)) = 0.939 Å ~~ 1Å`
X-rays cover wavelengths ranging from about `10^(-8)m (10 nm)` to `10^(-13)m (10^(-4)nm)`.
An electromagnetic radiation of energy 13.2 keV belongs to X-ray region of electromagnetic spectrum.
