The electromagnetic waves on one side of the visible band are called infrared radiation.

Here's a breakdown:

* Visible light is the portion of the electromagnetic spectrum that humans can see.

* Infrared radiation has a longer wavelength than visible light, meaning it has less energy.

* Ultraviolet radiation has a shorter wavelength than visible light, meaning it has more energy.

So, the visible spectrum is sandwiched between infrared and ultraviolet.
