Radiation

Back to front of school building

Radiation

The Earth gets lots of heat from the sun,
but there are no particles in space to
carry the heat to the Earth via conduction
or convection. All the heat from the sun
reaches Earth by radiation. Heat
radiation is a type of wave and it
behaves like light waves. Heat radiation
travels at the speed of light, it travels
in straight lines and it can travel
through a vacuum where there
are no particles, just like light.

I'm ready to find out which materials are good at radiating heat
