Question

In an experiment with a rectangular glass slab, a student observed that a ray of light incident at an
angle of 60° with the normal on one face of the slab, after refraction, strikes the opposite face of the
slab before emerging out in air making an angle of 42° with the normal. Draw a labelled ray diagram
to show the path of this ray. What value would you assign to the angle of refraction and angle of
emergence?​

Answer 1
