Newton’s Disk Manufacturer,Supplier and Exporter in India
Product Code : SCL-MH-12680
The Newton’s Disk by Educational Instrument India is a classic physics laboratory apparatus designed to demonstrate the composition of white light. It consists of a circular disc divided into different coloured sectors, usually representing the colours of the visible spectrum. When the disc is rotated rapidly, the colours blend together and appear nearly white, helping students understand that white light is made up of multiple colours.
This apparatus is ideal for school physics laboratories, STEM classrooms, science demonstrations, and educational training institutes. It provides a simple and visual method for teaching optics, colour mixing, visible spectrum, and the basic principles of light. Newton’s Disk is especially useful for demonstrating how the human eye perceives rapidly rotating colours as a combined colour.

How to Use Newton’s Disk
Place the Newton’s Disk apparatus on a stable and flat laboratory table.
Ensure that the coloured disc is properly fixed to the rotating spindle or stand.
If the apparatus is hand-operated, rotate the disc using the handle or string mechanism.
If the apparatus is motorized, connect it to a suitable power supply as per the model instructions.
Rotate the disc at a sufficiently high speed.
Observe how the different colours visually blend together and appear nearly white.
Explain that white light is composed of different colours of the visible spectrum.
Stop the rotation and allow students to observe the individual colours on the stationary disc.
After use, clean and store the apparatus safely in a dry place.
Educational Applications
Newton’s Disk is widely used in physics education to demonstrate the recombination of spectrum colours into white light. It helps students understand important optics concepts such as colour mixing, visible spectrum, light composition, and persistence of vision. The apparatus is suitable for classroom demonstrations, school science exhibitions, laboratory practicals, and STEM learning activities.
