A suntan is caused by the release of the pigment Melanin in the skin. This is the body's defensive response to harmful Ultraviolet radiation that makes up part of the Sun's rays. Ultraviolet is part of the Electromagnetic Spectrum.
The primary EM spectrum colors are red, green, and blue. These colors can be combined in different ways to create all the other colors we see in the visible spectrum.
Waves are a broad category on the electromagnetic (EM) spectrum that includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. They differ from each other in terms of their wavelength and frequency.
Electromagnetic (EM) waves are arranged in the spectrum based on their wavelength or frequency. From longest to shortest wavelength/frequency, the EM spectrum includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. This arrangement is important because each region of the spectrum has unique properties and interactions with matter.
Two properties of electromagnetic waves that change across the spectrum are wavelength and frequency. As you move from one end of the spectrum to the other, the wavelength decreases and the frequency increases.
The categories of the electromagnetic (EM) spectrum, in the ascending order of their frequencies are:RadioMicrowaveInfraredVisibleUltravioletX-rayGammaHence, Radio waves have the lowest frequency and the longest wavelengths while Gamma rays have the highest frequency and the shortest wavelengths.(check related link for an image)
Most of the EM spectrum is visible light.

Radio waves are the longest lengthwise.
Gamma rays
It is certainly a very important part, but it is not a major part; 'visible light' makes up only a tiny part of the EM spectrum.
Visible and infra red parts of the EM spectrum
Visible light is a very small part of the EM spectrum and it is intellectual laziness to refer to all EM radiation as light.
Only their wavelengths are different.
