==Key Stage 3==
===Meaning===
The '''refractive index''' of a [[medium]] is a [[measure]] of how much [[light]] slows down when it enters the [[medium]].
===About Refractive Index===
: A larger '''refractive index''' is a higher '''optical density''' and represents a slower speed of [[light]] through the [[medium]].
: A smaller '''refractive index''' is a lower '''optical density''' and represents a faster speed of [[light]] through the [[medium]].
==Key Stage 4==
===Meaning===
The '''refractive index''' of a [[medium]] is a [[measure]] of how much [[light]] slows down when it enters the [[medium]].
===About Refractive Index===
: A larger '''refractive index''' is a higher '''optical density''' and represents a slower speed of [[light]] through the [[medium]].
: A smaller '''refractive index''' is a lower '''optical density''' and represents a faster speed of [[light]] through the [[medium]].
: [[Light]] [[refraction|refract]]s when it enters a new [[medium]] due to the change in speed caused by the difference in '''optical density'''.
