# Identify the rays PE,EF,FS and angles r,D,e mentioned in the diagram.

Solution
Verified by Toppr

#### a) Incident ray - PEAn incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.b) Refracted ray - EFA refracted ray is a ray which has entered a medium and bent either away from the normal or towards the normal depending on the density of the new medium in comparison to the old one.c) Emergent ray - FSThe emergent ray is the ray of light which passes through a denser medium(glass) to a rarer medium(air).d) Angle of refraction - ∠rAngle of refraction is defined as the angle between the normal and the refracted ray.e) Angle of deviation - ∠DThe angle of deviation through a triangular prism is defined as the angle between the incident ray and the emerging ray.f) Angle of emergence - ∠eAngle of emergence is defined as the angle between the normal and the emergent ray.
