Silver Back

This simulation series is based on concept of Silvered lenses. A silvered lens is a lens with silver paint on one face. Light crosses the glass, reflects at the silver, and crosses the glass again. So the whole piece acts as one curved mirror. A separate mirror behind a lens acts in the same way.

What you'll learn

  1. Silver the flat face The flat face of a lens carries silver. Find where sunlight comes back to a point.
  2. Silver the curved face The curved face of a lens carries silver. Find where sunlight comes back to a point.
  3. In a liquid A silvered lens sits in a liquid. Find the radius that gives the wanted focus.
  4. Pin on its own image A pin stands in front of a silvered lens. Find the distance where its image lands on the pin.
  5. Lens and plane mirror A plane mirror stands behind a lens. Find where the candle must stand for a wanted image.
  6. Convex mirror behind A mirror stands behind a lens. Find the gap that brings the image back onto the pin.
  7. Mirror, then lens A pin sits between a mirror and a lens. Find the place that gives the wanted size.
