WebbSunlight is an example of radiant energy. It's something that we can see and feel (you feel warm when you stand in sunlight). Something that is not quite so obvious is that everyone in the classroom is emitting radiant energy. This is … WebbThe light emitting diode is the most visible type of semiconductor diode. They emit a fairly narrow bandwidth of either visible light at different coloured wavelengths, invisible infra-red light for remote controls or laser type light when a forward current is passed through them.

WebbFrom the energy distribution curve of black body radiation, the following conclusions can be drawn : (a) The higher the temperature of a body, the higher is the area under the curve i.e. more amount of energy is emitted by the body at a higher temperature. (b) The energy emitted by the body at different temperatures is not uniform. WebbRadiant energy can be transmitted in a vacuum environment, so the matter is not essential in transmitting radiant energy. Radiant energy is moving at a very high speed, straight …

WebbIn physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon 's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy ).
