Question

information about kaleidoscope

Answer 1

A kaleidoscope (US: /ˈkəlaɪdəskoʊp/) 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 viewed presenting.

Answer 2

$\:\:\: \huge{\underline{\boxed{\sf{Kaleidoscope - \: }}}}$

• Is a device that uses reflections to produce different patterns.

• It consists of three plane mirrors inclined at an angle.

• When kaleidoscope is rotated the mirrors form beautiful patterns of the objects placed in front of them due to multiple reflections.

$\:\:\: {\underline{\boxed{\sf{Principle: - \: }}}}$

• It is based on the principle of multiple reflections by the set of three plane mirrors inclined with each other at an angle of 60° .

$\:\:\: {\underline{\boxed{\sf{Uses : - \: }}}}$

(a) It can be used to make toys attractive.

(b) It is used by designers of wall papers and fabric.

(c) Artists also used it to get idea for new patterns.
