A periscope makes use of the property of reflection to redirect light. Light enters one end of the periscope, reflects off mirrors inside the periscope, and then exits at the other end, allowing the viewer to see objects outside their direct line of sight.
A periscope uses angled mirrors to reflect light at different angles, allowing it to travel around corners. The mirrors inside the periscope are set up to guide the light path from the object at one end to the observer's eye at the other end, creating the illusion that the observer is seeing directly in front of them.
