Question

Which of the following is true for kaleidoscopes?
1) Same pattern can't be seen twice
2) Same pattern is seen after equal intervals
3) Patterns are seen randomly
4) No pattern seen

Answer 1

Hint: Kaleidoscope is an optical device with reflecting surfaces inclined at angles therefore multiple reflections occur. It shows picture shaping properties of mirrors. It shows like hexagonally, octagons like positioned pictures.

Complete step by step answer:
A kaleidoscope is an optical instrument with at least two reflecting surfaces inclined to one another in a point, so at least one object toward one side of the mirrors are viewed as a normal balanced example when seen from the opposite end, because of repeated reflection. The reflectors or mirrors are generally encased in a cylinder, regularly containing toward one side a cell with free, shaded bits of glass or other transparent and additionally dark materials to be reflected into the saw design. Revolution of the cell causes movement of the materials, bringing about an ever-changing perspective being introduced.
The kaleidoscope shows the picture shaping properties of consolidated, slanted mirrors. In the event that an item is set between two mirrors slanted at right points, a picture is shaped in each mirror. Every one of these identical representations is thus reflected in the other mirror, shaping the presence of four evenly positioned objects. On the off chance that the mirrors are slanted at 60°, a hexagonally even example results from one article creating six consistently positioned pictures.
A straightforward kaleidoscope comprises two slim, wedge-molded mirror strips contacting along a typical edge or of a solitary sheet of brilliant aluminum bowed to a point of 60° or 45°. The mirrors are encased in a cylinder with a review eyehole toward one side. At the opposite end is a slim, level box that can be pivoted. In this container are bits of colorful glass, sparkle, or dabs. At the point when the case is turned or tapped, the items inside tumble into a discretionary gathering, and when the diffusing screen is enlightened, the six fold or eightfold increase makes a striking even example. The quantity of combinations and examples is viably unbounded and always different.
Option 1 is correct.

Note: Kaleidoscope basically works on the principle of multiple reflections and it gives rise to many unique images and it is used for entertainment purposes.
