: [[Incident Ray]] - A [[Light Ray|ray]] is called an [[Incident Ray|incident ray]] before it reaches the boundary between two [[Medium|media]].
: [[Refracted Ray]] - Once the [[Light Ray|ray]] passes the boundary it is called a [[Refracted Ray|refracted ray]].
: [[Normal Line|Normal]] - The [[Normal Line|normal line]] is an imaginary line drawn at [[Right Angle|right angles]] to the boundary between two [[Medium|media]].
: [[Angle of Incidence]] - The [[angle]] between the [[Incident Ray]] and the [[Normal Line|Normal]] is called the [[Angle of Incidence|angle of incidence]].
: [[Angle of Refraction]] - The [[angle]] between the [[Refracted Ray]] and the [[Normal Line|Normal]] is called the [[Angle of Refraction|angle of refraction]].
: [[Emergent Ray]] - When a [[Light Ray|ray]] enters and then leaves a new [[medium]] the [[Light Ray|ray]] that leaves is called an [[Emergent Ray|emergent ray]].
