Turn the Prism

This simulation series is based on concept of Refraction through a prism. A prism has two flat faces set at an angle. Light bends at each face, so the beam leaves in a new direction. The turn depends on the glass and on the prism's setting. At some settings the second face traps the light inside.

What you'll learn

  1. The least turn A prism turns a beam. Find the angle of incidence that turns it least.
  2. Turn equals the angle Choose a prism angle so the least turn comes out equal to that angle.
  3. A water prism A hollow prism holds a liquid. Find the least turn it gives the beam.
  4. In at an angle A beam enters a prism at a set angle. Find the angle it leaves at.
  5. Just gets out Some beams never leave a prism. Find the smallest entry angle that still gets out.
  6. Wet face A liquid touches one face of a prism. Find the index that makes the beam just graze that face.
  7. Straight back A prism has a silvered face. Find the entry angle that sends the beam straight back.
  8. Coat the back face A coating goes on a prism's second face. Find the index that just traps the beam.
