This apparatus demonstrates the discovery, made by Newton, that white light is made up of seven individual colours. The apparatus consists of a pulley mounted on a metal stand. The seven-coloured disc is driven by a belt connected to a hand-driven wheel. When the disc is rotated fast, the eye is unable to distinguish between individual colours and perceives it as white. * Demonstrates that white light is made up of 7 individual colours * When rotated fast, the eye is unable to distinguish colours and sees white https://elecena.pl/product/27206205/rapid-newton-s-colour-disc 2024-11-10 https://elecena.pl/product/27206205/rapid-newton-s-colour-disc 2025-01-04 https://elecena.pl/product/27206205/rapid-newton-s-colour-disc 2025-08-03 https://elecena.pl/product/27206205/rapid-newton-s-colour-disc 2026-04-29 https://elecena.pl/product/27206205/rapid-newton-s-colour-disc 2026-07-05
