Newton’s disk
Product Code : SCL-MH-12693
The Newton’s
Disk by Educational Instrument India is a classic
physics laboratory apparatus designed to demonstrate the composition of white
light. The disc is divided into multiple coloured sectors representing the
colours of the visible spectrum. When the disc is rotated at high speed, the
colours visually blend together and appear nearly white.
This apparatus is
ideal for school physics laboratories, STEM classrooms, science exhibitions,
and educational training institutes. It provides a simple, visual, and
effective way to teach students that white light is made up of different
colours. Newton’s Disk also helps explain colour mixing, optics, visible
spectrum, and persistence of vision.
Key Features
Designed to
demonstrate the composition of white light.
Shows how different
spectrum colours combine to appear white when rotated rapidly.
Useful for teaching
optics, colour theory, visible spectrum, and light composition.
Simple and visual
apparatus for easy classroom understanding.
Suitable for
physics labs, STEM classrooms, and science exhibitions.
Available in manual
or motorized models depending on requirement.
Durable
construction for repeated educational use.

How to Use Newton’s Disk
Place the Newton’s
Disk apparatus on a stable and flat laboratory table.
Ensure the coloured
disc is properly fixed to the spindle, stand, or rotating mechanism.
If the model is
hand-operated, rotate the disc using the handle or string mechanism.
If the model is
motorized, connect it to the recommended power supply.
Rotate the disc at
a sufficiently high speed.
Observe how the
individual colours visually blend together and appear nearly white.
Stop the disc and
allow students to observe the separate colour sectors again.
Explain that white
light is composed of different colours of the visible spectrum.
After use, clean
the apparatus and store it 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 optics concepts such as
colour mixing, visible spectrum, light composition, and persistence of vision.
The apparatus is useful for classroom demonstrations, school science
exhibitions, practical lessons, and STEM learning activities.
Why Choose Educational Instrument India Newton’s
Disk?
Designed for clear
and effective optics demonstrations.
Helps students understand
white light and colour mixing through visual observation.
Simple to operate
and suitable for classroom teaching.
Useful for physics
labs, STEM activities, and science exhibitions.
Reliable apparatus
for repeated educational use.
Safety Instructions
Use the apparatus
only under teacher or laboratory instructor supervision.
Do not touch the
disc while it is rotating.
Keep fingers, loose
clothing, hair, and small objects away from moving parts.
If using a
motorized model, connect only to the recommended power supply.
Stop the rotation
completely before adjusting or removing the disc.
Store the apparatus
in a clean and dry place after use.
FAQ
1. What is Newton’s Disk used for?
Newton’s Disk is
used to demonstrate that white light is made up of different colours of the
visible spectrum.
2. How does Newton’s Disk work?
When the coloured
disc rotates rapidly, the different colours blend together due to persistence
of vision and appear nearly white to the eye.
3. Is Newton’s Disk suitable for school laboratories?
Yes, Newton’s Disk
is suitable for school physics labs, STEM classrooms, science exhibitions, and
educational training institutes.
4. Which concepts can students learn from Newton’s
Disk?
Students can learn
about white light composition, visible spectrum, colour mixing, optics, and
persistence of vision.
5. Can Newton’s Disk be used for classroom
demonstrations?
Yes, it is an
excellent classroom demonstration apparatus because it gives a simple and
visual explanation of colour recombination.
