Scene 3 (25s)
[Audio] What is a kaleidoscope A kaleidoscope is an optical instrument with two or more reflecting surfaces or mirrors tilted to each other at an angle, so that one or more ( parts of) objects on one end of these mirrors are shown as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. These reflectors 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..

[Audio] History The kaleidoscope was invented by Sir David Brewster about 1816 and patented in 1817. Sold usually as a toy, the kaleidoscope also has value for the pattern designer. The kaleidoscope illustrates the image-forming properties of combined, inclined mirrors..

[Audio] How to make a kaleidoscope Step 1: Gather Materials Gather materials. Here is a list of what you will need 1-clear acrylic tube 10" long with a 1 1/4" inside diameter 3- mirror pieces 10" X 15/16".

[Audio] What is multiple reflection Multiple reflection of light is the reflection of light back and forth several times between reflecting surfaces. If a reflected light ray is reflected again on being incident on another surface, it is termed multiple reflections. Multiple reflections are used in periscopes..
