Before we dive deeper into the specifics of infrared heat, let's start with an overview of the three different ways that heat can be transferred:

Conduction - direct contact with the heat source. Convection - Heat transfer via air or water (eg, a radiator). Radiation - No transfer medium needed. Travels via invisible waves, like the heat from the sun.

Radiation is exactly ...

To best answer this question we first need to really understand: What exactly is infrared light?

You probably remember in school learning about the electromagnetic spectrum, or perhaps even using a prism to split light into its separate colours, forming a rainbow like effect. This prism of colours is 'visible light', that is, light that human eyes can actually detect. Also on this spe ...
