Describe the construction of a kaleidoscope.

A kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other at an angle, so that one or more objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection.


Working of a Kaleidoscope
 It consists of two or more reflecting surfaces. These surfaces are tilted towards each other at a certain angle to get symmetrical patterns when viewed from the other side. Colored pieces of glass are present in the tube that consists of reflecting surfaces. By rotating this tube, symmetrical images are created.  

The principle used in the kaleidoscope is the law of reflection. When a white light, which is a combination VIBGYOR, hits the surface of the mirror, it gets reflected at an angle such that the angle of incidence is equal to the angle of reflection. Because of these multiple reflections, beautiful images are created.
