The element emits infrared radiation that travels through air or space until it hits an absorbing surface, where it is partially converted to heat and partially reflected.

Their embedded elements emit heat to the inner container at a slow, steady rate, thereby allowing foods to literally cook all day, unattended.

This decay can be monitored and the element emitting identified by the identity and energy of the emitted particles.

Each element emits light at a characteristic wavelength, which is dispersed by a grating or prism and detected in the spectrometer.

The constituent elements of the sample absorb some of these neutrons and emit prompt gamma rays which are measured with a gamma ray spectrometer.

Most elements emit a narrow band of visible light.

This is why the element emits radiation, and why it's a natural choice for the induced fission that nuclear power plants require.

In fact, we now know each atomic element emits distinctive colors because of the jiggle of its electrons.

Different elements emit or absorb light at very special wavelengths, and thus leave their "signature" in the light coming from the star.

Different elements, when excited, emit fluorescent X-rays at different and characteristic energies, so this information indicates which elements are present.
