Answer 1

Answer:

Radiation is 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).

The radiation of sun is part of the electromagnetic spectrum, including infrared, visible, and ultraviolet light.
