Consider the following electromagnetic radiations: (I) Microwaves...

The electromagnetic spectrum in the order of decreasing wavelength is:

Radio waves $>$ Microwaves $>$ Infrared rays $>$ Visible light $>$ Ultraviolet rays $>$ X-rays $>$ Gamma rays

From the given options, the correct descending order of their wavelengths is:

Microwaves (I) $>$ Infrared rays (III) $>$ Ultraviolet rays (II) $>$ Gamma rays (IV)

Answer: $\text{(I)} > \text{(III)} > \text{(II)} > \text{(IV)}$
