An electromagnetic radiation has an energy 14.4 Kev. To which region of electromagnetic spectrum does it belong?
Answer & explanation
Correct answer: option 3
$\lambda=\frac{hc}{E}=\frac{6.6 \times 10^{-34} \times 3 \times 10^8}{14.4 \times 10^3 \times 1.6 \times 10^{-19}}$
This wavelength belongs to X-ray region.
