How does heat reach us from the Sun?

Question

How does heat reach us from the Sun?

OR

Explain the process of radiation?

OR

Explain the energy transfer of a body by radiation does not require a material medium and the rate of transfer is affected by:

Colour and texture of the surface
Surface temperature
Surface area

Accepted Answer

Radiations:

Radiation is the mode of transfer of heat from one place to another in the form of waves called electromagnetic waves.

Transfer of heat energy from the sun to earth:

Our Sun is the major source of heat energy. Sunlight reaches us neither by conduction nor by convection because the space between the Sun and the Earth's atmosphere is empty. There is a third mode called radiation by which heat travels from one place to another. It is through radiation that heat reaches us from the Sun.
