The periscope was invented in 1450 by Johann Gutenberg.
As a "periscope" is an instrument for seeing above a surface of some kind (usually water) from below it, its use will typically occur in sentences dealing with military, exploration, or scientific subjects. Just one example would be, "The submarine was discovered by the scout plane through a fortuitous accident: the sunlight flashed off the glass lens of its raised periscope, revealing its location below the surface."

Periscopes A periscope is a instrument of observation used for naval use or for other war-like purposes. In fact the first periscope prototype was made by Johann Gutenberg which was used to enable people to see over the heads of the crowd at the Vigintennial religious festival at Aachen. In the navy it is used in submarines to view possible threats such as enemy submarines or sea mines. Marie Davey built the first naval periscope, a simple, fixed periscope using mirrors in 1854. A periscope works by using two mirrors to bounce light from one place to another. A typical periscope uses two mirrors at 45 degree angles to the direction one desires to see. The light bounces from one to the other and then out to the person's eye.
