Question
Draw a labelled ray diagram to show how a ray of light passes through a parallel sided glass block:
  1. If it hits the glass block at 90° (that is, perpendicular to the glass block).
  2. If it hits the glass block at an angle other than 90° (that is, obliquely to the glass block).

Answer
