What is the difference?
- 1Design: Periscopes are typically longer and more tubular in shape, while spyglasses are shorter and more compact.
- 2Function: Periscopes are primarily used for seeing over or around obstacles, while spyglasses are used for viewing distant objects.
- 3Context: Periscopes are commonly associated with submarines, tanks, and other military vehicles, while spyglasses are often associated with pirates, sailors, and explorers.
- 4Magnification: Periscopes may have fixed or limited magnification, while spyglasses often have adjustable magnification.
- 5Usage: Periscopes are typically used in enclosed spaces, while spyglasses are used outdoors.
Remember this!
Periscope and spyglass are both optical instruments used for viewing distant objects. However, they differ in design, function, context, magnification, and usage. A periscope is a tubular device used for seeing over or around obstacles, often associated with military or nautical contexts. A spyglass is a handheld telescope used for viewing distant objects, often associated with pirates, sailors, and explorers.
