AI overview
A periscope is an optical instrument that uses mirrors or prisms to allow a person to see objects that are above or around obstacles by reflecting light into the observer's eye. It matters because it enables people in submarines, trenches, or other confined spaces to observe their surroundings without exposing themselves to danger.
