Answer;
D.
infrared, visible, ultraviolet
Explanation;
Electromagnetic waves are types of waves that do not require a material medium for transmission. An electromagnetic spectrum arranges these electromagnetic waves in the order of increasing frequency and decreasing wavelength.
The spectrum consists of , Radio waves, microwaves, infrared, visible light, UV light, X-rays and Gamma rays; arranged in order of decreasing wavelength and increasing frequency.
Radio waves have the longest wavelength but the lowest frequency, while gamma rays have the lowest wavelength but the largest frequency.
