Product Description
This Large Newton’s Disc is an optical instrument for demonstrating the additive synthesis of light. By rapidly rotating seven spectral colors, it visually synthesizes white light, illustrating the persistence of vision. It is used in physics laboratories and lecture halls to validate color theory through a physical experiment. Caution: the disc rotates rapidly during use — keep fingers and loose items clear of the rotating mechanism while it is in operation.

Frequently Asked Questions
What does this disc demonstrate?
The additive synthesis of light — how seven spectral colors combine visually into white light when rapidly rotated.
What visual effect makes this work?
The persistence of vision, which causes the rapidly rotating colors to blend in the viewer’s perception.
Is there a safety consideration?
Yes — the disc rotates rapidly during use, so keep fingers and loose items clear of the mechanism.
How should it be maintained?
Stored dust-free, with the mounting spindle handled carefully and rotation checked periodically.
