Summary[edit]
| Description |
English: Newtons Disc - Reverse RAINBOW
The Science behind this will show you how the colors of a Newton's disc blend together and are merged as a blended white light by our brains and eyes. The Newton disc is a well-known physics experiment and invented by Isaac Newton, my disc has six segments in rainbow colors. When the disc is rotated really fast, the colors fade to white; In this way Isaac Newton demonstrated that white light is a combination of the seven different colors found in a rainbow. Hence the reverse rainbow. I created Newton Disc with the six different colors. But you can do a combination of red, green and blue in the circular disc will yield the same result. This is due to the phenomenon called persistence of vision. It was an important discovery as it proves that light is not colorless, but has color in it which together converge to give a faded white color which we consider colorless. This property is based on the principles of dispersion of light. This experiment was final proof that white light is made up of all the colors of the visible spectrum. Red, orange, yellow, green, blue and violet… as well as the shades in between. |
