Question

How is the phenomenon of reflection used in making a kaleidoscope? What are the applications of a kaleidoscope?

Answer 1

Hint: Kaleidoscope is an optical instrument used in optical applications and is based upon the principle of reflection of light.

Complete step by step answer:
The kaleidoscope uses mirrors. Long thin mirrors are arranged in such a fashion that they face one another. Usually, there is no limitation on the number of mirrors say 8-10 are used in making a small kaleidoscope but in actual the number of mirrors to be used depending upon the desired end pattern to be achieved.
There are two ends, one end contains the objects to be reflected. The end of the kaleidoscope is closed off with glass or plastic can also be used. When viewed from viewing side light filters through the glass and it undergoes multiple reflections before coming out of the kaleidoscope. As light bounces off different mirrors, the eye sees the bouncing reflections, creating the patterns. And when the kaleidoscope rotates the tiny objects inside shift the chambers and as a result, our eye sees different patterns. In such a manner reflective of light, multiple ways help to create patterns.
Applications:
1. They are used as an optical toy for children.
2. In fashion designing, different patterns are created with the help of a kaleidoscope.
3. It can also be used as a teaching aid by mathematics teachers to teach geometry.

Note:
Early uses of kaleidoscope were for the sole purpose of entertainment but now they are finding roles in different fields.
Kaleidoscope is a long tunnel sometimes round and also in triangular shapes.
