Glass Globe

This simulation series is based on concept of Refraction at a curved glass face. A curved glass face bends light by itself, with no lens and no mirror. The bent light then makes an image at a new place. Where that image forms depends on the curve and on the glass.

What you'll learn

  1. Sunlight into a rod Sunlight runs into a glass rod with a curved end. Find where the rays meet inside.
  2. Pin outside the rod A pin stands in front of a curved glass end. Find where its image forms.
  3. How tall inside A pin stands in front of a curved glass end. Find the height of its image.
  4. Grind the end A pin must give a real image of a chosen size inside a rod. Find the radius of the end.
  5. As far in as out The image inside must be as far in as the pin is out. Find the pin's place.
  6. Glass ball Sunlight falls on a solid glass ball. Find where the rays meet beyond it.
  7. Two rods, one gap Light passes from one glass rod into another. Find the gap that makes the rays run parallel.
  8. Under the dome A mark sits under a glass block with a domed top. Find how deep the mark seems.
