Hello friends ,in this video, we have talked about
Newton's disc as follow:
The Newton disc, also known as the Disappearing
Colour Disc, is a well-known physics experiment with
a rotating disc with segments in different colours
(usually Newton's primary colours : red, orange,
yellow, green, blue, indigo, and violet or ROYGBIV)
appearing as white (or off-white or gray) when it
spins very fast.
This type of mix oflight stimuli is called temporal
optical mixing, a version of additive-averaging
mixing.The concept that human visual
perception cannot distinguish details of high-speed
movements is popularly known as persistence of
vision.
The disc is named after Isaac Newton. Although he
published a circular diagram with segments for the
primary colors that he had discovered, it is uncertain
whether he actually ever used a spinning disc to
demonstrate the principles of light.
We have explained in a simple way ,hoping that it will
helpful to you.
