Newton disc was invented by the great scientist Isaac Newton. This experiment basically consists of 7 colors in a single disc.
These colors are rainbow colors. When the disc is rotated, the colors fade into a white color.
Thus, in simple terms, Newton mentioned that the white light is a combination of the seven colors of the rainbow.
This whole process or result is based on the principle of dispersion of light. This also follows a simple concept called
This means that when the disc moves very fast at a certain speed, the stimuli cannot differentiate between the colors and it looks like a white light.
In this video, we show a simple working model of Newton disc using materials that are easily available at home.
- Small toy fan
- Small running battery
- Cardboard with 7 colours of the rainbow attached in a circle(disc)
You use the resource/tools page section to find the tips where you can buy these materials used at a reasonable cost.

Questions and Answers:
- What is a newton disc experiment?
A. Newton disc experiment explains that when a disc made of seven colours of a rainbow moves very fast in a circular motion or rotates very fast, it appears that the disc is a white colour. This is because the stimuli can see it as a white light based on the concept of optical mixing.
2. What is the principle behind newton disc?
A. The Newton disc is based on a simple concept called as optical mixing where any two or more lights when together cannot be distinguished emitting like a white light or a single colour light to the stimuli. This is very different from the concept of physical mixing of the lights.
3. Explain the importance of the concept of newton disc?
A. Newton’s disc theory was developed to demonstrate the persistence of vision.
Newton disc experiment is also called as
The perception of the
It is based on a theory of optical mixing and additive
