WebRadiation is the transfer of heat through electromagnetic waves through space. Unlike convection or conduction, where energy from gases, liquids, and solids is transferred by the molecules with or without their physical movement, radiation does not need any medium (molecules or atoms). Energy can be transferred by radiation even in a vacuum. WebObserve how heat is transferred 1. Show how heat travels through 1. Shows that heat travels through air. Objectives 2.
