Prism with Variable Angle

This prism with variable angle was used to study how the angle of deviation of a beam of light increases with the refracting angle of the prism. The glass plates which make up part of the prism can move about their hinged bottom edge. Water is placed in the prism, a beam of light is directed through it, and then the angle of the prism can be changed by sliding the glass between the brass sides.
