Explanation: 

Detailed explanation-1: -EXPLANATION: From the above table it is clear that the correct order is “Radio waves > > Infrared rays > Visible Light > X-Rays”.

Detailed explanation-2: -The electromagnetic spectrum arranged according to decreasing wavelengths: Microwaves > Infrared > Visible light > UV rays > Gamma rays.

Detailed explanation-3: -In order of decreasing wavelength or increasing frequency these are: radio waves radiation, microwave radiation, infrared, visible light, ultraviolet, X-rays, and gamma rays.

Detailed explanation-4: -Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, gamma rays, and cosmic rays are the different regions of the electromagnetic spectrum. They are arranged in the order of decreasing frequency and rising order of wavelength.

Detailed explanation-5: -Microwave > Infrared > Ultraviolet >Gamma ray.
