A kaleidoscope is an optical device used to produce multiple patterns of images.

Its a cylinder with three plane mirrors and loose, coloured objects such as beads/pebbles and glass bits.

[{"selector":"#anim-b2e716af-7b2d-4931-b89b-e9cc63c2e8f7","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-f0665435-9b1e-437a-b78b-a07ce3ff1bd5","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] Thus, one or more parts of objects on one side of the mirrors are seen as a regular symmetrical pattern when seen from the other end.

There are 2 principles used in a kaleidoscope: – The law of reflection – The fact that white light is a combination of VIBGYOR

[{"selector":"#anim-6fb1a150-606b-43b5-8a3a-948277bcf81a","keyframes":{"opacity":[0,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-3dcf75d2-f094-4dd4-a566-a628b0275779","keyframes":{"transform":["scale(0.3333333333333333)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] When the white light hits the surface of the mirror, the reflection happens at an angle such that the angle of incidence and the angle of reflection are equal.

[{"selector":"#anim-c87033bb-e43a-47fc-aa7c-abbd3e5863e5","keyframes":{"opacity":[1,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-e92c151d-e7c9-4adf-bd91-01309a329e05","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] This reflection process takes place multiple times and creates beautiful & colourful patterns.

[{"selector":"#anim-fc108f99-3b71-4e37-bd4c-092de1b0d42e","keyframes":{"opacity":[1,1]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"both"}] [{"selector":"#anim-167a8e46-ffa2-4d1c-8c5d-f0247c09093e","keyframes":{"transform":["scale(3)","scale(1)"]},"delay":0,"duration":1300,"easing":"cubic-bezier(.3,0,.55,1)","fill":"forwards"}] Also, according to the second principle, the coloured objects in the kaleidoscope absorb most of the white light when the light passes through them.

Isn’t that amazing?
