How fast does radiated heat travel
WebHow does radiation work? Once molecules on the surface of an object absorb heat rays, they vibrate rapidly. The vibration generates frictional heat within the object. At no time does the radiating body come into direct contact with the object, yet heat energy is transferred from one to the other. WebWe know that infrared waves are also called heat waves. Heat radiations use electromagnetic waves to transfer heat from one body to another body. The speed of an …
