Describe the construction of a kaleidoscope.

Hint: A Kaleidoscope is an optical instrument with two or more reflecting surfaces. These reflecting surfaces are tilted at an angle, so that one or more objects at one end of the mirrors can be seen as a regular symmetrical pattern when viewed from the other end of the minor. In this instrument we used the phenomena of repeated reflection.

Complete step-by-step answer:
Kaleidoscope is an instrument which works on the principle of multiple reflections. Basically it consists of three long plane mirrors tilted at an angle \[60{}^\circ \] to one another and formed prisms. These three narrow strips of plane mirrors. Fitted in a tube one end of this tube is closed by an opaque sheet and another sheet is covered with a transparent sheet to see the objects there is an eye hole in the opaque sheet. The glass is filled with bits of glass. When a Kaleidoscope is covered, we get to see various patterns in it. These patterns are formed because of multiple reflections.
    

Construction of Kaleidoscope

Note:
Kaleidoscope is the instrument in which the same type of pattern we cannot see again. It gives a different pattern every time. It happens due to multiple reflections of light by the tilted formation of narrow strips of plane mirror.
