A beam of light travellig in a reactangular glass slab emerges into air. Draw a ray-diagram indicating the change in its path.

A beam of light travelling in air is incident on water. Draw a ray-diagram indicating the change in its path in water.

A ray of light travelling in air is incident on a parallel-sided glass slab(or rectangular glass slab). Draw a ray-diagram indiciating the change in its path in glass.

A ray of light travelling in air incident on a rectangular glass block and emerges out into the air from the opposite face. Draw a labelled ray diagram to show the complete path of this ray of light. Mark the two points where the refractions of light takes place. What can you say about the final direction of ray of light?

A ray of light travelling in air is incident on a rectangular glass slab. What will happen?

A ray of light passes through a rectangular glass block placed in air. Which diagram shows a possible path of a ray?

A ray of light enters a rectangular glass slab of refractive index sqrt(3) at an angle of incidence 60^(@) . It travels a distance of 5cm inside the slab and emerges out of the slab. The perpendicular distance between the incident and the emergent rays is

A student does the experiment on tracing the path of a ray of light passing through a rectangular glass slab for different angles of incidence. He can get a correct measure of the angle of incidence and the angle of emergence by following the labelling indicated in figure :

In the experiment on tracing the path of a ray of light passing through a rectangular glass slab, the correct setting of the protractor (D), for measuring the angle of incidence ( angle I ), and the angle of emergence ( angle e ) correspond, respectively, to diagrams :
