radiation 

Radiation uses high-energy particles or waves

Examples of Radiation : A burning candle emits radiation in the form of heat and light. The Sun emits radiation in the form of light, heat, and particles. Heat moves in three ways: Radiation, conduction, and convection. Radiation happens when heat moves as energy waves, called infrared waves, directly from its source to something else. This is how the heat from the Sun gets to Earth. In fact, all hot things radiate heat to cooler things.
