Key Stage 3
Meaning
Absorption is when the energy being transferred by a wave is taken into an energy store of a material.
Key Stage 4
Meaning
Absorption is when the energy being transmitted by a wave is taken into an energy store of a material.
About Absorption
- When a wave is absorbed the wave ceases to exist and the energy being transmitted by that wave increases an energy store of the absorbing material.
- Absorption happens at the interface between two media.
- Black objects absorb light increasing their thermal energy store.
- Soft objects absorb sound increasing their thermal energy store.
- The colour of an object is caused by some frequencies of light being absorbed while others are reflected.

Key Stage 5
Meaning
Absorbtion is the process where matter takes in photons, particles, or energy.
About Absorption
- Absorbtion involves the transfer of energy from the electromagnetic wave to the material.
- It can occur in various forms, such as the absorption of light, sound, or radiation.
- Materials have specific absoption spectra indicating which wavelengths they absorb.
Examples
- Solar panels absorb sunlight to convert it into electricity.
- Dark-coloured objects absorb more visible light and therefore heat up faster than light-coloured objects.
