5..Make a simple PERISCOPE by placing two mirrors in a ‘Z’ shaped

box​

Answer 1

Find two small mirrors the same size. You can use any flat mirrors, whether the frame is rectangular, round, or some other shape. The two mirrors don't even have to be the same shape, but they do need to be small enough to fit into a milk carton.

You may be able to find small mirrors at a craft or art supply store, or from an online store.

periscope allows you to look over at objects or people from around a corner, or from a higher vantage point than normal. While modern submarines and other high-tech vehicles usually use a more complex system of prisms and lenses, the basic mirror periscope described below is easy to make at home, and provides a clear enough image that it was widely used for military purposes well into the twentieth century

How to make a periscope with CD or DVD

Step 1 Cut the mirror. We can thank Shannon of Victoria BC, Canada for the idea of using ordinary CDs for the two mirrors.

Step 2: Cut out the periscope body and the triangle mounts. Go here and print out the body pattern.

Step 3: Fold and tape.

Step 4: Tape the mirrors to the mounts, and the mounts to the periscope.

Plane mirrors are used in a reflecting periscope. Two plane mirrors are fixed at the bends of the tube at an angle of 45o with the side of the tube.

You need two mirrors for one periscope.
