Best Answer

Periscopes are optical devices that allow you to look at objects that are not in the straight line of vision. It usually consists of a metal tube with mirrors within it usually tilted 45 degrees as shown below. Thus the object around a corner can be viewed. Used mostly in submarines. It allows sailors submerged under water to see and monitor what is happening above water. See any World War II movie with submarines or Walt Disney’s “Twenty Thousand Leagues Under The Sea” and you can see a periscope in action.
