What types of mirror are used in kaleidoscope?

Kaleidoscopes typically use two or more flat mirrors arranged at an angle to one another, often 60 or 45 degrees, to create symmetrical patterns. These mirrors reflect light and images from objects placed inside the kaleidoscope, producing vibrant and intricate designs. Some kaleidoscopes may also incorporate curved mirrors to enhance the visual effects, but flat mirrors are the most common type used.
