Vedclass · Answer

(B) The energy $E$ of a photon is related to its wavelength $\lambda$ by the formula $\lambda = \frac{hc}{E}$.Given,$E = 15\, keV = 15 	imes 10^3\, eV$.The value of $hc$ is approximately $1240\, eV\, nm$.Substituting these values,we get $\lambda = \frac{1240\, eV\, nm}{15 	imes 10^3\, eV} \approx 0.083\, nm$.The wavelength range for $X$-rays typically spans from $1\, nm$ to $10^{-3}\, nm$.Since $0.083\, nm$ falls within this range,the electromagnetic waves belong to the $X$-ray part of the spectrum.

The energy of the electromagnetic waves is of the order of $15\, keV$. To which part of the spectrum does it belong?
