Draw a ray diagram to illustrate how a ray of light incident obliquely on one face of a rectangular glass slab of uniform thickness emerges.

Draw a diagram to show the reflection of a light ray incident normally on a plane mirror.

A ray of light travelling obliquely from glass to air :

A beam of light composed of red and green ray is incident obliquely at a point on the face of rectangular glass slab. When coming out on the opposite parallel face, the red and green ray emerge form

In the adjacent diagram, AO is a ray of light incident on a rectangular glass slab. (a) Complete the path of the ray till it emerges out of the slab. (b) In the diagram, mark the angle of incidence (i) and the angle of refraction (r) at the first interface. how is the refractive index of glass related to the angles i and r ? (c) Mark angle of emergence by the letter e. how are the angles i and e related ? (d) Which two rays are parallel to each other ? Name them (e) Indicate in the diagram the lateral displacement between the emergent ray and the incident ray. state one factor that affects the lateral displacement.

(a) Deduce the expression, by drawing a suitable ray diagram, for the refractive index of a triangular glass prisms in terms of the angle of minimum deviation (D) and the angle of prism (A). Draw a plot showing the variation of the angle of deviation with the angle of incidence. (b) Calculate the value of the angle of incidence when a ray of light incident on one face of an equilateral glass prism produces the emergent ray, which just grazes along the adjacent face. Refractive index of prism is sqrt2

A ray of light is icncident at anangle of 60^@ on one face of a ractangular glass slab of thickness 2sqrt(3) mm refractive index sqrt(3) , Calculate the lateral shift produced in mm.

In the diagram below, PQ is a ray of light incident on a rectangular glass block. How are the angles i and 'e' related to each other?
