When the white light from the source falls on the surface of the mirror, the incident white light is reflected at an angle which is equal to the angle of the incident. Thus the angle of incidence and angle of reflection of the white light is equal to each other. And the presence of the glasses and mirrors cause multiple reflections inside the kaleidoscope. The beautiful image patterns are created due to this multiple reflection formed inside the kaleidoscope. When the white light from the source falls on the surface of the mirror and other glasses, the most part of the light gets absorbed by the mirrors and colored glasses.
