Vedclass · Answer

(A) The energy of a photon is given by $E = \frac{hc}{\lambda}$.Rearranging for wavelength: $\lambda = \frac{hc}{E}$.Given $E = 11 \, keV = 11 	imes 10^3 	imes 1.6 	imes 10^{-19} \, J$.Using $hc = 12400 \, eV \cdot \mathring{A}$,we have $\lambda = \frac{12400 \, eV \cdot \mathring{A}}{11000 \, eV} \approx 1.13 \, \mathring{A}$.The wavelength range for $X-$rays is approximately $0.1 \, \mathring{A}$ to $100 \, \mathring{A}$.Since $1.13 \, \mathring{A}$ falls within this range,the radiation belongs to the $X-$ray region.

List-$I$	List-$II$
$(1)$ $700\, nm$ to $1\, mm$	$(i)$ Vibration of atoms and molecules
$(2)$ $1\, nm$ to $400\, nm$	$(ii)$ Inner shell electrons in atoms moving from one energy level to a lower level
$(3)$ $< 10^{-3}\, nm$	$(iii)$ Radioactive decay of the nucleus
$(4)$ $1\, mm$ to $0.1\, m$	$(iv)$ Magnetron valve

Photons of an electromagnetic radiation have an energy of $11 \, keV$ each. To which region of the electromagnetic spectrum does it belong?
