the base firmly in place. Pencil marks are easily erased from
the table’s white surface, so you can mark angles and trace
rays directly on it.
Equipment Setup
Set up a light source or ray box to project a single ray. Place
the light source and the ray table close together on a lab bench

Place the D-shaped lens over the lens outline on the ray table.
Note that the flat surface of the lens is aligned with the “Com-
