A periscope works by using two mirrors positioned at a 45-degree angle to each other. When you look into one end of the periscope, light from the scene above the surface reflects off the first mirror and travels to the second mirror, which reflects it down to your eye. This allows you to see over obstacles or around corners without being directly in the line of sight. Periscopes are commonly used in submarines and other applications where visibility is limited.
