Answer Details
The plane mirrors in a kaleidoscope are usually placed at an angle to one another. This angle can vary but is often around 60 degrees. This angle creates a repeating pattern of reflections, which creates the beautiful and intricate designs that kaleidoscopes are known for. The mirrors need to be angled so that the reflections overlap and create a continuous pattern. The mirrors can be made of glass or plastic and are coated with a thin layer of reflective material, such as aluminum, which allows for the reflection of light to create the patterns.
