Key Stage 3
Meaning
Radiation is an energy transfer that spreads the energy by waves starting from a central point.
About Radiation
- Light is a radiation that can transfer energy from one energy store to another.
- Sound is a form of radiation that transfers energy by pressure waves through a solid, liquid or gaseous medium.
Key Stage 4
Meaning
Radiation is an energy transfer that spreads the energy by waves starting from a central point.
NB: Radiation should not be confused with Ionising Radiation. Most radiation is harmless. Ionising Radiation is extremely dangerous.
About Radiation
- Radiation can transfer energy through a medium.
- The energy transferred by radiation increases with the intensity of the radiation. Loud sounds transfer more energy than quiet sounds. Bright light transfers more energy than dim light.
- Radiation can be harmful depending on the intensity. The greater the intensity the more harmful it can be.
