Periscope vs. Telescope: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 3, 2023
A periscope allows viewing over, around, or through an object, obstacle, or surface; a telescope magnifies distant objects, typically in the sky.

Key Differences
Periscopes employ mirrors or prisms to see over obstacles, primarily used in submarines and during warfare. A telescope, however, is designed to observe distant celestial bodies and is fundamental in astronomy for studying space.

The periscope's basic principle is the reflection of light, which allows the observer to see from a protected or concealed position. In contrast, the telescope uses lenses or mirrors to gather and focus light from faraway objects, making them appear closer and clearer to the observer.

Periscopes are practical for navigation and tactical purposes in marine and land-based applications. Telescopes serve both amateur and professional astronomers in exploring and understanding the universe, contributing significantly to scientific discovery.

With a periscope, the focus is on redirecting the line of sight. The telescope's function is to collect more light than the human eye can, allowing detailed observation of faint and distant objects such as stars, planets, and galaxies.

A periscope is simple in design, often portable, and can be used in real-time to observe surroundings without exposure. Telescopes are usually more complex, larger, and are used for stargazing, tracking celestial events, and scientific research.
