Vedclass · Answer

(A) The electromagnetic spectrum in increasing order of frequency (or decreasing order of wavelength) is: Radio waves > Microwaves > Infrared > Visible > Ultraviolet > $X$-rays > Gamma rays.Given:$\lambda_{1}$ = Short radio waves$\lambda_{2}$ = $X$-rays$\lambda_{3}$ = Ultraviolet wavesComparing their positions in the spectrum,the wavelength order is: $\lambda_{1} > \lambda_{3} > \lambda_{2}$.Therefore,the correct decreasing order is $\lambda_{1}, \lambda_{3}, \lambda_{2}$.

List-$I$	List-$II$
$(a)$ Ultraviolet rays	$(i)$ Study crystal structure
$(b)$ Microwaves	$(ii)$ Greenhouse effect
$(c)$ Infrared waves	$(iii)$ Sterilizing surgical instruments
$(d)$ $X$-rays	$(iv)$ Radar system

The wavelengths of short radio waves,$X$-rays,and ultraviolet waves are $\lambda_{1}$,$\lambda_{2}$,and $\lambda_{3}$ respectively. Arrange them in decreasing order.
