Assalamu alaikum warahmtaulahi wabarakatu!

As you probably guessed already this is another post about my “Tell me what” book! What is a kaleidoscope is a very interesting topic I wanted to share with you. If you love different patterns and colors then you’ll love this post inshallah! Soooo, here goes!

A kaleidoscope resembles a short telescope with a rotating end-piece. When you look through a kaleidoscope, you will see a colourful, geometric pattern. Twisting the end-piece creates ever-changing, mesmerizing new patterns. A kaleidoscope consists of two or more mirrors laid lengthwise inside a tube. Colored beads, liquid-filled ampules or other small objects reside in the larger end of the tube.

The viewer looks in one end and light enters the other end, reflecting off the mirrors. Typically, there are two rectangular lengthways mirrors. Setting off the mirrors at 45 degrees creates eight duplicate images of the objects, six at 60 degrees and 4 as 90 degrees. As the tube is rotated, the tumbling of the colored objects presents the viewer with varying colors and patterns.

Any arbitrary pattern of objects shows up as a beautiful symmetric pattern because of the reflections in the mirrors. Some sources claim that the kaleidoscope was known to ancient Greece, but the Scottish inventor, David Brewster, is credited with it’s modern invention in 1816.

A prism is a transparent optical element with flat, polished surfaces that refract light.
