Furthermore, fashion designers use the beautiful patterns created by a kaleidoscope.įor making a kaleidoscope, and enjoying its various patterns of different colours, you need to keep in mind that it works on the principle of reflection. The handmade pieces of a kaleidoscope display fine craftsmanship and artistic skills and are often available at craft galleries and also at the enterprises specializing in them. Most of the kaleidoscopes are mass-produced from several inexpensive materials and intended as an optical toy for children consisting of two mirrors placed at a particular angle. As a result of the multiple reflections of light, there is a creation of beautiful and innovative patterns.
Due to this most of the light gets absorbed by these objects. According to the second principle, the white light, a combination of seven colours, passes through the coloured objects in a kaleidoscope. When the light falls on the surface of a mirror, it gets reflected in a way that the angle of incidence is equivalent to the angle of reflection. The laws of reflection and the fact that white light is a combination of VIBGYOR (Violet Indigo Blue Green Yellow Orange Red) form the basis of the underlying principle of a kaleidoscope. Sir David Brewster was certain that this object was a marvel and can be put to great use, an object that can create “Infinite Patterns”, so he applied for the patent for a new optical instrument and named it “Kaleidoscope”. Brewster took the last step and he placed reflecting panes in a tube along with a concave lens which would show the objects nearby and we would be able to see them in a reflected pattern. Among them was a great man, Sir Goerge Makenzie and he was sure that this is going to be very popular in the years to come.
When some members of the Royal Society of Edinburgh saw an earlier version, they were highly impressed. This prompted him to conduct further experiments and to find the perfect situations for a clear and symmetrical pattern. This amazed him but he let the thought rest when again in 1815 he carried out an experiment where the reflections multiplied as a bit of cement was pushed towards the end and the light was thrown via a triangular glass. At first, a candle was placed and a circular arrangement of various images of the candle was noted. In these experiments, successive reflections were made on the plates of glass. This journey of making a masterpiece started in 1814 when some experiments were conducted on the topic of ‘light polarization’ by Sir David Brewster. It has been a source of creativity for designers to design various pallets, has been a toy with which all of us have played and it’s an integral part of our childhood memories, for jewellers it has led to the making of marvellous designs. Since the time of its invention by Sir David Brewster, there are various functions that have been fulfilled by the kaleidoscope. The tubes with mirrors are magic and art on their own. The kaleidoscope opens a way of imagination, travel, and creating designs. If we place the inclined mirrors at 60 degrees, a symmetrical hexagonally pattern forms six regularly placed images. Each mirror is needed to be inclined at right angles so that each image is reflected in the other mirror forming an appearance of four symmetrically placed objects. When we place an object in between these two mirrors an image is formed. The designs/images are formed due to the inclined mirrors. The kaleidoscope is usually sold as a toy and has value for the designs. A Scottish inventor, David Brewster, invented the kaleidoscope in 1817 and patented it in 1817. The term 'kaleidoscope' is derived from the Ancient Greek words known as 'kalos' which means beauty, 'eidos' means something that is seen and 'skopeo' which means to look. The tube, which has reflecting surfaces, contains coloured pieces of glass, and if we rotate the tube, we see that symmetrical images are created. This happens due to the phenomenon of repeated reflection. As an optical instrument, a kaleidoscope contains two or more reflecting surfaces tilted towards each other at a certain angle for obtaining a symmetrical pattern when viewed from the other end.
