Isaac Newton:
Isaac Newton is one of the most famous scientists in physics and mathematics through the ages and one of the symbols of the scientific revolution, and he is the discoverer of the Earth’s gravity and the inventor of the “Newton’s disk”, one of his most famous books is “optics (1704)”
Newton’s disk:
Is one of the inventions of the world's famous scientist "Isaac Newton" .discovered it when he was in his laboratory doing experiments on the light until the sunlight hit one of the bottles and the colors of the rainbow appeared and here came the idea of "Newton's disk"
History:
On 6 February 1671/72 Isaac Newton wrote a paper about the experiments he had been conducting since 1666 with the refraction of light through glass prisms. He concluded that the different refracted rays of light - well parted from others - could not be changed by further
Refraction, or by reflection or other means,
Except through mixture with other rays. He thus found the seven primary colors: red, yellow,
green, blue, purple, orange and indigo.
The White Color:
In his book “Opticks (1704)” Newton describes a device with prisms, a lens and a large moving comb with teeth causing alternating colors to be projected successively. "But if I so much accelerated the Motion, that the Colors by reason of their quick Succession could not be distinguished from one another, the Appearance of the single Colors ceased. There was no red, no yellow, no green, no blue, nor purple to be seen any longer, but from a Confusion of them all there arose one uniform white Color."
Installation of a Newton disc:
This is how to make Newton’s disk:
The tools are: Motor-A disk colored with rainbow colors-Battery-Switch.
Operation: Place the disc in the motor needle from the center. Connect the motor, power switch and battery by wire. Operate the engine with electricity. The disc rotates and shows the white color.
