All light (or more technically, electromagnetic radiation) is waves. Light waves have different frequencies. Ultraviolet light waves have a frequency higher than light waves in the visible spectrum (the frequencies humans can see). Infrared light waves have a freqency lower than light waves. The terms come from the fact that violet has the highest frequency in the visible spectrum, and red the lowest.

Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of seen gentle, yet shorter than that of radio waves. The call means "under purple" (from the Latin infra, "under"), purple being the colour of seen gentle of longest wavelength. Infrared radiation spans 3 orders of value and has wavelengths between approximately 750 nm and a million mm.[a million] Ultraviolet (UV) gentle is electromagnetic radiation with a wavelength shorter than that of seen gentle, yet longer than delicate X-rays. it is subdivided into close to UV (380–200 nm wavelength; abbrev. NUV), an prolonged way or vacuum UV (200–c4ca4238a0b92382dcc509a6f75849b0 nm; abbrev. FUV or VUV), and severe UV (a million–3c4ca4238a0b92382dcc509a6f75849b nm; abbrev. EUV or XUV).

Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of radio waves. The name means "below red" (from the Latin infra, "below"), red being the color of visible light of longest wavelength. Infrared radiation spans three orders of magnitude and has wavelengths between approximately 750 nm and 1 mm.[1]
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than soft X-rays. It can be subdivided into near UV (380–200 nm wavelength; abbrev. NUV), far or vacuum UV (200–10 nm; abbrev. FUV or VUV), and extreme UV (1–31 nm; abbrev. EUV or XUV).

infrared and ultraviolet are light waves that we cannot see with our eyes. Ultra violet is powerful and can burn us. It comes from various sources - the sun, florescent lights, etc... infrared light is generally harmless and is used in things like tv remotes and nighttime cameras.

They are part of the electromagnetic spectrum, along with visible light. Infrared is lower energy then visible light, and ultraviolet is higher energy then visible light.

They are part of the electromagnetic spectrum, along with visible light, radio, microwaves, gamma and X rays. They differ by their amounts of energy.

I dont think so that there are any such thing!
