Additional Info

• ID Code: N1-44
• Purpose: Demonstrates internal reflection and dispersion of light
• Description: A single light ray is focused by a convex lens to limit its width. The ray enters a plastic disc, which models the water drop, is reflected internally and returns at an angle of about 40 degrees. The dispersion is apparent at a distance from the drop, so the light can be cast on a wall or a distant screen to see the colors.
