The colour of the dis when rotating is white it was an experiment to prove that white light was actually made of different colors and that experiment shows that if you get all the colours moving and spining fast enough it looks as if the light is white

What is the use of newton's color disk?
isaac newton's colour disk shows that white light isn't really,it is a mixture of seven colours that are violet,indigo,blue,green,yellow,orange and red.
What is the device that reads from and writes to a floppy disk or hard disk?
a computer
What are the functions of a hard disk?
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
How does a strobe light work?
2. A strobe light works by illuminating an object with a very brief flash of light. If this flash of light is repeated at the same rate as an object is rotating, then the rotating object will appear to be stationary. The flash of light is produced by a flash tube similar to that on a modern camera, but one capable of having a very short pulse of light, and at very great intensity. The modern Strobe light was invented by Edgerton, and he went on to invent Side Scan Sonar, a powerful technique for viewing the seabed. The primitive origin of the strobe light can be seen as a slit in a cardboard disk, which is rotation at the same speed as the object is rotating. The technique is not limited to rotating machinery - any repetitive motion may be studied. And with single flashes, a short-lived phenomena may be captured on film.
What is Intraocular disk?
is it a lens !!
Why earth is rotating?
it is due to presence of debris disk around sun
What is crank Design and Tegnology?
crank is nothing but disk and it is a rotating part and it is couple with crank shaft
What is blu ray disc?
Any color ... the "blue" does not refer to the color of the disk but to the laser light that reads the disk.
Why is it necessary to mention the axis of rectangular bar while calculating the moment of inertia?
An object rotating about its long axis will have a different moment of inertia than when it is rotating about its short axis. A solid disk will have a different moment than a washer, and there are formulas derived for calculating the moments of many common shapes.
Parson standing on an rotating disc straches his hand outside then what happens to speed?
Well, the "Parson" on the rotating disk would get very dizzy and would not be able to continue with his sermon. As he stretched his hand outwards to bless his congregation the spin speed of the disk would slow.
What is the colour Blu-ray disc?
Any color ... the "blue" does not refer to the color of the disk but to the laser light that reads the disk.
Does disk and drum brakes work exactly the same?
No. Drum brakes expand inside a rotating drum to stop the vehicle, disc brakes squeeze in against a rotating disc.
The fact that the primeval nebula was rotating slightly caused?
It caused the solar system to form in the shape of a disk.
What is the name of a device that has a rotating center pin hard to explain do have a picture though?
Disk? top? gyroscope?
What is The disk of dust and gas that formed the sun and planets called?
The disk of dust and gas that formed the Sun and planets is known as the solar nebula.The dense concentration of gas at the center of this rotating disk eventually became the Sun.
Before the planets were formed the inner part of the rotating disk was what and the outer part was what?
The part of the rotating disk within the frost line was formed of rocks and metals. The part beyond the frost line had both the materials within the frost line as well as some gasses such as hydrogen an helium.
What are floppy disketters?
Floppy diskette drives read and write information to a single rotating disk that can be removed from the drive.
