Infra-red.
The human eye can only detect electromagnetic radiation in the visible spectrum, Typically, wavelengths of 390 to 750 nm fall within the visible spectrum. Radiation with these wavelengths are called visible light or simply light.
Spectroscopy is basically the study of the spectrums of visible and non-visible light rays. Specifically, it is determining the output of radiation an object has along the spectrum. This is called a wavelength.
Electromagnetic radiation with wavelengths between visible light and X-rays is called ultraviolet radiation. It is known to have shorter wavelengths and higher energy than visible light, and is commonly associated with effects like sunburn and skin damage from excessive exposure.
Infrared has a longer wavelength, and a lower frequency, than visible light.
An invisible Electromagnetic radiation (also called solar radiation) whose wavelength is shorter than visible light but greater than X-rays (i.e in ORDER of 10-8 m) is called ultraviolet wave.
Electromagnetic radiation having a wavelengths between 380 - 750nm is visible to the normal human eye. This region of the spectrum is called visible light. Radiation of any other wavelength cannot be seen with the naked eye

Visible light waves
It is a consequence of something called blackbody radiation. Any object that is not at absolute zero emits electromagnetic radiation. The higher the temperature the cooler At temperatures we usually fin on Earth that radiation is in the infrared range. Hot enough objects emit much of their radiation as visible light. The coolest stars emit mostly red light, which has the longest wavelength of visible light. The hottest stars are blue, as blue light has a shorter wavelength.
It is literally called visible light..

Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.
