A kaleidoscope, a popular toy that produces colorful, symmetrical patterns when rotated, relies primarily on which optical principle?

Explanation

A kaleidoscope produces its distinctive, ever-changing symmetrical patterns primarily through the reflection of light off multiple mirrors angled toward each other inside the tube, which repeatedly reflect and multiply the image of small, often colorful, loose objects or beads placed at one end. As the kaleidoscope is rotated, these small objects shift and tumble, continuously changing the resulting reflected pattern seen through the eyepiece. The basic underlying design of the kaleidoscope, invented in the early nineteenth century, remains largely unchanged in most modern versions of the toy.
