Kaleidoscope image with 3 mirrors4/3/2023 You can also study reflection using two small square glass mirrors taped together on one side. Tape the 3rd side closed, then use tape to connect the envelope towards the finish from the kaleidoscope. Cut two triangles of the transparent substance, just like a plastic overhead transparency, to suit another finish tape up two edges to create a three-sided envelope, and set chocolate sprinkles and/or items of colored paper inside. Learn about light and optics by making your own kaleidoscope. Like a microscope or telescope, the optics in a kaleidoscope enhance our vision. 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. Keep your second triangular upside lower to ensure that there’s enough room backward and forward transparencies for that plastic to slot in.Īs 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. Now, put the coloured plastic in the finish from the kaleidoscope, that has the transparency paper, and add some other transparency paper, the triangular (bigger size).

To help students see how to do each step before they make their own kaleidoscope, consider running though each of the steps as mini demos for the class to follow along.Learn Kaleidoscope – Application & Uses topic of Physics in details explained by subject experts on.Ensure that you allow enough time for the students to both construct and experiment with their kaleidoscopes. This make and take takes time, especially for younger students.Put your eye to the eyepiece and turn or shake the kaleidoscope to see the patterns created by the multiple reflections.Cover the outside with colourful tape, wrapping paper or other decorations.Turn the tube over, and create a safe eyepiece lining the edges of the mirror tube with electrical tape, or by totally covering the end in electrical tape and carefully opening up an eyehole with a pin.Cover it with a piece of wax paper and tape it securely onto the triangular tube.There should be room for the beads to tumble around. into the indentation you formed in step 4. Add colourful beads, sequins, sparkles, paper, etc.Wrap a strip of lightweight card stock around the same end of the tube, making sure it extends a few millimetres beyond the top.Cover one end of the tube with plastic wrap, pulling it taut and taping it firmly around the perimeter of the tube.Use elastic bands (or a friend) to hold the mirrors in place while you securely tape them together around the outside of the tube.Assemble the three pre-cut mirrors with the reflective sides facing inward to form a triangular tube.Selection of colourful beads, sequins, sparkles or bits of shiny paper Describe how light rays can change direction.ĭemonstrate how visible light is reflected.ģ mirrors 4.5cm x 11 cm *can be purchased through craft/hobby stores
