About This Product
With the disc fixed in place, it is spun quickly so the class sees the separate colours merge into an almost white surface, then stopped so the sectors can be seen again. The demonstration links the recombination of spectrum colours to persistence of vision and suits practical lessons and science exhibitions. Laboratories and colleges in South Africa, Philippines, Malta, South Korea, Haiti and Saudi Arabia can buy the Newton’s disk through an export order.
Frequently Asked Questions
Why does Newton’s Disk look white when it spins?
The coloured sectors represent the visible spectrum, and at high speed the eye blends them, so the disc appears nearly white.
