The Photo on the RIGHT Shows the Rings Projected by the Apparatus.

Instructions / Notes:

• Demonstration includes a projector lamp, a Newton's Rings set of glass plates, and a projection lens.
• The beam of light shines from the projector bulb and is reflected back by the Newton's Rings glass plates.
• This reflected light is projected through the lens on to a blank wall.
• Note: Avoid keeping the light on for extended periods of time. The bulb has a tendency to heat up!
