Question

In an experiment with a rectangular glass slab, a student observed that a ray of light
incident at an angle of 55" with the normal on one face of the slab, after refraction
strikes the opposite face of the slab before emerging out into air making an angle of
40 with the normal. Draw a labelled diagram to show the path of this ray. What value
would you assign to the angle of refraction and angle of emergence?​
