A periscope is used to observe the surface from a submarine
PERISCOPE
The medical term for an instrument used to view small objects is "microscope." It is commonly used in various medical fields for examining cells, tissues, or microorganisms at a magnified level.
A periscope is the instrument used in a submarine to see above the surface of water. It works by using mirrors to reflect light down into the submarine while allowing for observation of the surface without exposing the submarine itself.

A microscope is an instrument used to magnify minute objects. It works by combining a system of lenses, illuminators, and various techniques to achieve magnified views of small specimens or structures. Microscopes are widely used in scientific research, medical diagnostics, and education to study objects at the microscopic level.
Microscope - an instrument used for viewing objects that are too small to be seen by the naked eye. Kaleidoscope - a tube of mirrors containing loose, colored objects such as beads or paper, whose reflections produce changing patterns when the tube is rotated. Periscope - an instrument on a submarine or ship for seeing above the water or the horizon.
sonar is a device used underwater for locating submerged objects and for submarine communication by means of sound waves.

The instrument used in submarines to observe the surface of water is called a periscope. A periscope consists of a long tube with mirrors at each end, allowing the viewer to see objects above the water's surface while the submarine remains submerged. The periscope's mirrors reflect light from the surface down the tube to the viewer, providing a view of the surroundings without the need to surface the submarine.
