General Definition of ‘Radiate’
At its core, the word ‘radiate’ means to emit or send out something typically energy, light, or heat in the form of rays or waves. The origin of the word comes from the Latinradiatus, meaning ‘beaming’ or ’emitting rays.’

Scientific Context of Radiate
In the sciences, especially physics and environmental studies, ‘radiate’ has a specific, measurable meaning. It is used to describe how energy moves away from a source. For instance, the sun radiates light and heat to the Earth, making life possible. Likewise, a fire radiates warmth, affecting its surroundings without necessarily needing physical contact.

Radiation can be both natural and man-made. The term ‘radiate’ helps describe how this energy spreads in space or through various mediums.
