This, in turn, creates a symmetrical pattern due to the repeated reflections. So kaleidoscope translates to ‘observation of beautiful forms’.Ī kaleidoscope is an optical instrument with two or more reflective surfaces tilted towards each other at an angle. Eidos means ‘that which is seen’ (form and shape). It was discovered by a Scottish inventor, David Brewster.īrewster derived the name from ancient Greek terms.

But, it wasn’t until 1815 that the full kaleidoscope effect was realised. A ray incident on one mirror at angle, θ after reflection falls.Reflecting patterns through mirrors has been around for hundreds of years.
Two plane mirrors are inclined at 70 ∘. The critical angle for glass-water boundary is C. The phenomenon involved in the reflection of radio-waves by ionosphere is similar to?. Two plane mirrors are inclined to each other ray of light incident on one face at 30 ∘ after reflection…?. A ray of light from a denser medium strikes a rarer medium at an angle of incidence I. A cord attached to a vibrating tuning fork is divided into six segments under tension…?. One of its refracting surfaces is silvered. An object is placed at a distance 20cm from the pole of a convex mirror of focal length…?. Yellow light is used in a single slit diffraction experiment with slit width of 0.6 mm. A wave has velocity u in medium P and velocity 2u in medium Q. Two plane mirrors A and B are aligned parallel to each other, as shown in the figure. White light is incident on the interface of glass and air as shown in the figure. This will be through the multiple reflections of the single slice appearing side by side. Now, if you place the slice of pizza within two mirrors that are kept adjacent to each other at an angle, you will be able to see almost the entire pizza. In order to understand what happens in a kaleidoscope, imagine a pizza. Each slice of the pizza depicts the object put within the triangular area at the edge of the tube. Place the second triangle upside down so that there is enough space for plastic to move between the two transparencies.Īnd, once you are done with the making of kaleidoscope, you can design it beautifully with glitters, colours and so on. Attach another triangular transparent paper that is larger than the first one. Step 7: Place the colored plastic pieces at the end of the kaleidoscope that has transparent paper. Take some small paper cuttings that can be placed on the transparent paper. Step 6: Select the kind of plastic colour you would want to have inside the kaleidoscope. Step 5: Draw another triangle, but this time make it 2 cm larger than the earlier one. Step 4: Now, fix the paper into a separate place. Cut thin openings at the corners for easier folds. Step 3: After that, place the transparent paper at the edge of the Kaleidoscope. 
Step 2: Sketch the small triangle that is present at the edge of the kaleidoscope to the transparency paper (keep 1 cm extra around the triangle for allowing folding of the paper).
Make sure that it is solid and taped to the exterior of the triangle. Step 1: Get three mirror pieces and roll them in the form of a triangle.
