==Key Stage 4==
===Meaning===
[[Reflection]] is when a [[wave]] bounces off the [[interface]] between two [[medium|media]].
===About Reflection===
: All [[wave]]s can be '''reflected''' (eg [[Light|Light Waves]], [[Water Wave]]s, [[Ultrasound|Ultrasound Wave]]s, [[X-ray]]s).
: [[Reflection]] takes place at the [[interface]] between two [[medium|media]].
: For [[opaque]] [[material]]s [[reflection]] depends on the [[colour]] of the [[material]]. Rough [[opaque]] [[material]]s such as paper will [[Diffuse Reflection|diffusely reflect]] and smooth [[opaque]] [[material]]s will [[Specular Reflection|specularly reflect]] such as [[metal]]s.
: For [[transparent]] [[material]]s the chance of [[reflection]] at an [[interface]] depends upon the relative [[property|properties]] of those two [[medium|media]] and the [[Angle of Incidence]]. [[Wave]]s that arrive at an [[interface]] where there is a large difference in [[density]] or [[Refractive Index|refractive index]] are more likely to be '''reflected'''.
: [[Electromagnetic Wave|Electromagnetic waves]] travelling through a more [[Optical Density|optically dense]] [[medium]] will engage in 'total internal reflection' at the [[interface]] with a less [[Optical Density|optically dense]] [[medium]].
===The Law of Reflection===
: The Law of '''reflection''' states that the [[Angle of Incidence|angle of incidence]] is equal to the [[Angle of Reflection|angle of reflection]].

|}
===Specular and Diffuse Reflection===
: [[Reflection]] of [[Electromagnetic Wave]]s can be [[Specular Reflection|specular]] or [[Diffuse Reflection|diffuse]].
: [[Specular Reflection]] happens from a shiny, smooth surface and makes an [[image]].
: [[Diffuse Reflection]] happens from a dull, rough surface sending the [[Reflected Ray|reflected rays]] in different directions.
