ABOUT kaleidoscope
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.
Uses
this is for printing of bedsheets , clothes , etc
Invention
The kaleidoscope was invented by the Scottish scientist David Brewster and first publicly announced in 1817. This article is the first published element of a broader research project that discusses the changing meanings attached to the kaleidoscope during the past two hundred years.
Explanation:
What is a Kaleidoscope?
A kaleidoscope is an optical instrument consisting of two or more reflecting surfaces. These surfaces are tilted towards each other at a certain angle to obtain symmetrical patterns when viewed from the other end. The tube with reflecting surfaces consists of coloured pieces of glass. By rotating the tube, symmetrical images are created.
The word kaleidoscope is derived from the Ancient Greek word called “kalos” meaning “beautiful beauty”, “eidos” meaning “that which is seen” and “skopeo” meaning “to look”. David Brewster, a Scottish inventor, invented kaleidoscope on July 10, 1817.
In a kaleidoscope, the sunlight is bounced by the glass, and coloured beads present inside and are reflected in the mirrors to create magnificent picturesque patterns. These patterns offer an excellent visual treat to the person who looks through the kaleidoscope. It’s fun to watch and observe the mixing and matching pattern created insides the kaleidoscopes.

Principle Of Kaleidoscope
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.
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.
Kaleidoscope Uses
Kaleidoscope is an optical toy consisting of two mirrors at a particular angle. Some common uses of the kaleidoscope are:
Kaleidoscope produces beautiful patterns that are used by fashion designers.
A kaleidoscope is used as a toy for entertainment.
How to Make A Kaleidoscope?
Create a kaleidoscope and enjoy the various colours and patterns. Kaleidoscope works on the principle of reflection. Let us learn how to make a kaleidoscope.
Things you will need:
Plastic (See-through and coloured)
Overhead Transparency Paper
Pencil
Masking/Duct tape (One Roll)
Mirrored Perspex (3 Pieces)
How to do it?
Use the three pieces of mirrored perspex and roll them as tape in the form of a triangle. Try to ensure that it has a solid and it is taped on the outside of the triangle.
Sketch the small triangle located at the edge of the kaleidoscope to the overhead transparency paper (set aside 1 cm extra around the triangle to allow folding of the paper).
Keep the transparency paper to the kaleidoscope edge and cut the narrow openings at the corners, which would facilitate the folding of the corners easily.
Attach the paper into a separate place.
Make another triangle by drawing it, and this time it should be 2 cm larger than the earlier one
Choose the kind of plastic colour you would like to put inside the kaleidoscope. Take off small paper cuttings that would sit well on the transparent paper.
Place the coloured plastic at the end of the kaleidoscope that has a transparency paper and add another transparency paper (triangle) a little bigger than the earlier one. Keep the second triangle upside down so that there would be ample space for plastic to shift between the two transparencies.
Once you have finished making the kaleidoscope, design it beautifully with colours, glitters and so on
