Optical instruments like the periscope and kaleidoscope use the property of multiple reflections between plane mirrors in order to create the final image or images. In a periscope, two mirrors are placed at an angle of 45∘ with respect to the frame of the periscope such that the mirrors are parallel to each other.

What is kaleidoscope physics?

kaleidoscope, optical device consisting of mirrors that reflect images of bits of coloured glass in a symmetrical geometric design through a viewer. The design may be changed endlessly by rotating the section containing the loose fragments. The mirrors are enclosed in a tube with a viewing eyehole at one end.
