Describe the construction of a kaleidoscope.
Answer
A kaleidoscope is made up of three rectangular mirror strips joined together to form a prism. These are fix in a circular cardboard like tube or tube of a thick chart paper. The tube is slightly longer than the mirror strips. One end of the tube remains closed by a cardboard disc having a hole in the centre, through which one can see. To make the disc durable, a piece of transparent plastic sheet is pasted under the cardboard disc. At the other end, touching the mirrors, a circular plane glass plate is fixed. On this glass plate several small pieces of coloured glass is placed to form multiple images.
