Vedclass · Answer

(D) The energy of the given electromagnetic radiation is $E = 14.4 keV = 14.4 	imes 10^3 eV$.Electromagnetic radiation with energy in the range of $100 eV$ to $100 keV$ corresponds to the $X$-ray region of the electromagnetic spectrum.To verify,we calculate the wavelength $\lambda$ using the formula $\lambda = \frac{hc}{E}$:$\lambda = \frac{6.626 	imes 10^{-34} J \cdot s 	imes 3 	imes 10^8 m/s}{14.4 	imes 10^3 	imes 1.602 	imes 10^{-19} J} \approx 0.86 	imes 10^{-10} m = 0.86 Å$.Since the wavelength range for $X$-rays is typically $0.1 Å$ to $100 Å$ (or specifically $0.1 Å$ to $1 Å$ for hard $X$-rays),the radiation belongs to the $X$-ray region.

An electromagnetic radiation has an energy $14.4 keV$. To which region of the electromagnetic spectrum does it belong?
