Each bead
in the glass case acts as both a prism and a mirror, reflecting
light and separating it into a spectrum of rainbow colors. When
a light is shined on the case, white light enters each bead, reflects
off the bead and leaves again. White light is made up of many different
colors of light. A glass bead bends each of these colors at a different
angle, dispersing the white light into its component colors. As
a result every bead produces its own tiny spectrum or rainbow. However,
the eyes can see only one of the colors produced by a single bead.
The rest of the colors from the bead are bent so far that they never
enter the eyes.
