In this video we'll take a look at thermal radiation, one of the three modes of heat transfer along with conduction and convection. We'll start by covering electromagnetic waves, the Stefan ...

Because no particles are involved, radiation can work through the vacuum of space. This is why we can still feel the heat of the Sun even though it is 150 million km away from the Earth.

This points out a weakness of GaInAs-based sensors: in order to reduce the noise in the signal from thermal radiation, they are generally cooled down using a cryogenic cooler or similar solution.

Thermophotovoltaics (TPV) is a power generation technology that uses thermal radiation to generate electricity in photovoltaic cells. A TPV system generally consists of a thermal emitter that can ...

A black body completely absorbs all electromagnetic radiation that falls on it irrespective of its wavelength. When such a body is in a state of heat equilibrium, it emits radiation, such as light or ...
