==Key Stage 3==
===Meaning===
[[Reflection]] is when a [[wave ]] bounces off a surface.
===About Reflection===
: All [[wave]]s can be '''reflected'''.
: The [[reflection]] of [[sound]] is called an [[echo]].
===The Law of Reflection===
: [[Specular Reflection]] happens from a shiny surface and makes an [[image]] (you can see a 'reflection').
: [[Diffuse Reflection]] happens from a dull surface and is how we see all [[object]]s.

==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]].
: The chance of [[reflection]] at an [[interface]] depends upon the relative [[property|properties]] of those two [[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'''.
: The [[reflection]] of [[sound]] is called an [[echo]].
===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]].

| style="height:20px; width:200px; text-align:center;" |The [[angle]] between the [[Incident Ray|incident ray]] and the [[normal]] ([[Angle of Incidence|angle of incidence]]) is the same as the [[angle]] between the [[Reflected Ray|reflected ray]] and the [[normal]] ([[Angle of Reflection|angle of reflection]]).

===Specular and Diffuse Reflection===
: [[Reflection]] of [[Electromagntic 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.
