Question

Kaleidoscope works on the principle of:
A. Reflection of light from spherical mirrors
B. Multiple refraction of light from spherical mirrors
C. Multiple reflection of light from plane mirrors
D. Reflection of light from plane mirrors

Answer 1

Hint: Kaleidoscope works on laws of reflection.

Complete step by step solution:
A kaleidoscope is an optical instrument with two or more reflecting surfaces tilted to each other in an angle, so that one or more (parts of) objects on one end of the mirrors are seen as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. The reflectors (or mirrors) are usually enclosed in a tube, often containing on one end a cell with loose, colored pieces of glass or other transparent (and/or opaque) materials to be reflected into the viewed pattern. Rotation of the cell causes motion of the materials, resulting in an ever-changing view being presented.

Hence the option C is the correct option.

Additional Information:The basic principles used in the kaleidoscope are the law of reflection and white light is a combination of VIBGYOR. When the white light 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. Due to these multiple reflections of light, there is a creation of these beautiful patterns

Uses: Kaleidoscope is an optical toy consisting of two mirrors at a particular angle. Some common uses of the kaleidoscope are:
1. Kaleidoscope produces beautiful patterns that are used by fashion designers.
2. A kaleidoscope is used as a toy for entertainment.

Note: According to the second principle, white light passes through the coloured objects present in the kaleidoscope so that most of the light is absorbed by these objects.
