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

In an experiment, the path of a ray of light passing through a rectangular glass slab was traced by a student. Which of the following diagram shows correct measurement of angle of incidence (i), refraction (r ), and emergence (e ) ?

A ray of light falls normally on a rectangular glass slab. Draw a ray diagram showing the path of the ray till it emerges out of the slab.

In the diagram below, PQ is a ray of light incident on a rectangular glass block. Copy the diagram and complete the path of the ray of light through the glass block. In your diagram, mark the angle of incidence by letter 'i' and the angle of emergence by the letter 'e'.
