Perfect Patterns of Kaleidoscope க ல ட ஸ க ப ப ன சர ய ன வட வங கள

A kaleidoscope (, kəˈlaɪdəskoʊp, ) 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 everchanging view being presented. Kaleidoscope, optical device consisting of mirrors that reflect images of bits of coloured glass in a symmetrical geometric design through a viewer. In 1814 Sir David Brewster conducted experiments on light polarization by successive reflections between plates of glass and first noted the circular arrangement of the images of a candle round a center, and the multip
