Electric Newton’s disk

Product Code : SCL-OS-12829

The Electric Newton’s Disk by Educational Instrument uses a rotating multi-colour spectrum disc to show how separate colours visually blend when the disc spins at high speed. During rotation, the colours appear nearly white because the human eye retains visual impressions briefly, a phenomenon known as persistence of vision.

This apparatus is suitable for teacher-led demonstrations in optics, general science, and STEM learning. The electric rotation helps maintain steady speed compared with hand-operated models, making the colour-mixing effect easier for a full classroom to observe. Exact motor rating, material, size, and power requirement should be confirmed before final publication.

Key Features

Motorized operation: Electric rotation provides a steady demonstration of colour recombination.

Clear optics concept: Shows how spectrum colours combine visually to produce near-white appearance.

Classroom-friendly design: Useful for physics labs, STEM lessons, practical demonstrations, and science fairs.

Demonstrates persistence of vision: Helps students understand how the eye perceives rapidly changing colours.

Reusable teaching apparatus: Suitable for repeated supervised educational use.

Simple observation method: Students can compare stationary colour sectors with the rotating blended effect.

Capacity not applicable: This is an optics demonstration model, not a volumetric measuring instrument.

How to Use the Electric Newton’s Disk

Place the Electric Newton’s Disk apparatus on a clean, dry, and stable laboratory table.

Confirm that the coloured disc is securely fixed to the rotating spindle.

Connect the apparatus only to the recommended power source specified by the supplier.

Switch on the motor and allow the disc to rotate smoothly.

Ask students to observe how the separate colours blend and appear nearly white.

Switch off the apparatus and let the disc stop completely.

Compare the stopped coloured sectors with the rotating visual effect and explain the recombination of spectrum colours.

Safety note: Do not touch the rotating disc. Keep fingers, hair, loose clothing, wires, and small objects away from moving parts. Use the apparatus only under teacher or laboratory instructor supervision.

Care & Maintenance

Disconnect the power source before cleaning, adjusting, or storing the apparatus.

Clean the disc and base with a soft, dry cloth after use.

Store the unit in a dry cabinet to protect the printed colour sectors and electrical parts.

Inspect the motor, spindle, wiring, and plug before each demonstration.

Frequently Asked Questions

What is an Electric Newton’s Disk apparatus used for?

An Electric Newton’s Disk apparatus is used to demonstrate that white light is formed by the recombination of different colours of the visible spectrum.

How does an Electric Newton’s Disk work?

The coloured disc rotates at speed using an electric motor. The separate colours visually blend due to persistence of vision and appear nearly white to the observer.

Is Electric Newton’s Disk suitable for school laboratories?

Yes. It is suitable for supervised school physics labs, STEM classrooms, science exhibitions, and introductory optics demonstrations.

What concepts can students learn from this apparatus?

Students can learn white light composition, visible spectrum, colour mixing, additive colour perception, optics, and persistence of vision.

Does the Electric Newton’s Disk have a capacity?

No. Capacity is not applicable because this product is a physics optics demonstration apparatus, not a measuring cylinder, flask, or volumetric instrument.

What power supply does the Electric Newton’s Disk require?

The power supply should be confirmed for the exact model before publishing or purchasing. The apparatus should be connected only to the recommended power source.
