1.Okay, got the stuff? ... We�ll proceed then. Cut out your cardboard into four shapes like the ones below. Note the size of each compared to each other. This is important, that�s why we drew a grid, to make it a little more obvious. (The colours are not important it�s just there to help your know where each bit goes )
2.Right, now we�ve done that lets tape the shapes together into a tube like that shown below.
You can see, if you already had a cardboard tube how you can modify yours to look like the one below
3.Next step tape the mirrors onto the ends of the tube as shown, we should have pointed out that you need mirrors bigger than the end on your tube but then, we didn�t how big your tube was did we?
4.Look though one end with the other end held high
No

The periscope has several parts: the ocular lenses, the mirror or prism, inversion/reversion prisms, relay lenses, another mirror or prism, and objective lenses.
plane mirror
A periscope is an optical instrument that uses a system of prisms, lenses, or mirrors to reflect images through a tube. Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye.
Tape a mirror to the inside of each flap. cut away the side of the cardboard opposite each flap. Angle both mirror flaps inward about 30 degrees. Look through the bottom of the periscope to see that what is seen on the top mirror is also reflected on the bottom mirror.
A periscope works using two mirrors placed at 45 degree angles and in the direction you wish to see. A periscope uses the two mirrors to bounce light from one place to another. The light comes through the lense, bounces off one mirror to the other and then into the person's eye.
The submarine's periscope and radar mast are damaged.
The periscope has a reflector to make the light turn corners
Light from a distant object strikes the top mirror and is then reflected at an angle of 90 degrees down the periscope tube. At the bottom of the periscope, the light strikes another mirror and is then reflected into the viewer's eye. hope this helped :>
The basic periscope uses flat mirrors, to bend and offset the optical path. If magnification is required, then the periscope will use convex objective and eyepiece lenses, becoming a refracting telescope with an offset in its optical path.
In a tube, the light will bounce off on a 45 degree mirror twice until it will reach your sight.
