Detailed explanation-1: -When the colour wheel provided with this activity spins, the colours being reflected are changing faster than the photoreceptors can communicate with the brain. This means the reflected colours blend with each other and you see white light.

Detailed explanation-2: -As the color wheel spins, the colors mix together and blend into each other. If the wheel spins fast enough, the blending of the colors creates almost white light – a reflection of all colors of light at nearly the same time. As the wheel slows, you can perceive the distinct color being reflected by each section.

Detailed explanation-3: -How does that happen? Light is all of the colors in one: white. When the wheel spins up to the right speed, the colors blend into a near-recreation of white light. This “white” wheel is created because your eyes cannot keep up with the rapid rate at which the individual colors are spinning!

Detailed explanation-4: -White light is comprised of all the colours of the visible spectrum. i.e. red, orange, yellow, green, blue, indigo and violet… as well as the shades in between. Spinning the disc mixed all the different wavelengths of coloured light together, creating white light.
