When ==Key Stage 3=====Meaning==='''Absorption''' is when the [[energy]] being [[Energy Transfer|transferred]] by a [[wave]] is taken into an [[Energy Store|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|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|energy store]] of the '''absorbing''' [[material]].: '''Absorption''' happens at the [[interface]] between two [[media]].: Black [[object]]s '''absorb''' [[light]] increasing their [[Thermal Energy Store|thermal energy store]].: Soft [[object]]s '''absorb''' [[sound]] increasing their [[Thermal Energy Store|thermal energy store]].
