Question

define incident ray,refracted ray and emergent ray through a triangular glass prism




please answer ​

Answer 1

Answer:

When a beam passing through an object like glass prism it gets deflected twice, once while entering into glass prism and secondly when exiting from the prism. The sum of these two deflections is known as deviation angle or angle of deviation.

Answer 2

incident Ray

An incident Ray is a ray of light Thai strikes a surface. The angle between this Ray and the perpendicular or normal to the surface of the angle of incidence

reflected Ray

The reflected Ray corresponding to a given incident Ray, is the Ray that represents the light reflected by the surface

Emergent Ray through a triangular glass prism

when an incident Ray of light enters a prism gets refracted towards the normal. this refracted Ray then strikes the other face of prism and further deviates
