What is a kaleidoscope? A detailed explanation
What is a Kaleidoscope is a good question. It is a simple and old childrens toy. Even the ancient Greeks are said to have used a kaleidoscope. The word comes from the Greek and roughly means "beautiful seer".
- However, it only found use again in modern times when the Scottish physicist David Brewser accidentally discovered the application in 1816. Brewser observed crystals in a mirrored metal tube. The beautiful photographs tempted him to register a patent for the popular Childrens Toy .
- The kaleidoscope works through a series of different glass plates. The tube has a peephole at one end and a frosted glass plate at the other. Behind the latter are colorful movable glass parts.
- The colored parts are located between two glass plates. The rear one is matte, so that enough light falls into the tube for reflection. The front one is transparent so that the eye can clearly see the colors.
- There are three or four mirror strips in the tube that touch lengthwise. The particles thus move between these mirrored edges at the end of the tube. The colors of the particles are reflected so numerously.
- Now look through the pipe, you will see a colored pattern that constantly changes as you rotate the pipe.
