Visible light
The full range of wavelengths of electromagnetic radiation is called the electromagnetic spectrum. It includes radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays.
Humans can see visible light, which is a form of electromagnetic radiation with wavelengths between 400-700 nanometers. This range of wavelengths is detected by the photoreceptor cells in our eyes and processed by the brain to produce the sensation of sight.
The entire range of frequencies or wavelengths of electromagnetic radiation is called the electromagnetic spectrum. It includes radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays. Each type of radiation has a unique range of frequencies and wavelengths.

The collection of wavelengths is called the electromagnetic spectrum. It includes all forms of electromagnetic radiation, from radio waves to gamma rays.
Radiation that we can see is called visible light. It is a form of electromagnetic radiation that our eyes are able to detect, consisting of various wavelengths that our brain interprets as colors. Visible light allows us to see the world around us and is just one small part of the electromagnetic spectrum.
Electromagnetic radiation with medium wavelengths is called infrared radiation. This type of radiation has wavelengths longer than visible light but shorter than microwaves. Infrared radiation is commonly associated with heat and is used in various applications such as thermal imaging and remote controls.
The wavelengths of incoming solar radiation are shorter than the wavelengths of reradiated heat.
The visible spectrum of the electromagnetic spectrum of radiation
Visible radiation (a.k.a. light) is the wavelengths we can see. Infrared radiation lies down below the red end of the spectrum that we can see, hence infra red. But we can make device that both generate and detect infra red radiation. Your TV control works this way.
Our eyes are only sensitive to a specific range of wavelengths called visible light. Wavelengths outside this range, such as radio waves or X-rays, are not detectable by our eyes. Each type of electromagnetic radiation interacts differently with matter, so they require specialized instruments to be detected.
