Infrared is one, radio waves are another and many include microwaves as a third but microwaves are used for communications and are a form of radio wave. Wavelengths between radio waves and infrared are called TeraHertz radiation. Radio waves start at very long wavelengths LF or low frequency defined as 30kHz to 300kHz, MF or medium frequency from 300kHz to 3MHz, HF or high frequency from 3MHz to 30MHz, VHF or very high frequency from 30MHz to 300MHz, UHF or ultra high frequency from 300MHz to 3GHz and SHF from 3GHz to 30GHz. After that they are normally just called microwaves. Many microwave ovens operate near 2.4GHz which is only UHF.

It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.
The human eye can detect electromagnetic radiation in the visible region of the spectrum only. This region extends to the radiations of wavelength of 7600-3800 Angstrom
Blue light is in the visible wavelength range.
violet
380nm to 750nm.
Infrared radiation.
Blue light is in the visible wavelength range.
It is electromagnetic radiation whose wavelength is longer than that of visible light.
Infrared is longer.
Radio, microwaves, radar, and infrared radiation have.
It is electromagnetic radiation just like radio, microwaves, visible light etc.. except it has the highest frequency and energy and shortest wavelength of all electromagnetic radiation.
Visible light is a form of electromagnetic radiation that is visible.
