Question

which type of device enables its users to see around corners?
laser
telecope
microscope
fiber optics

Explanation:

• A laser is a device that emits light through a process of optical amplification. It is not used for seeing around corners.
• A telescope is used to view distant objects in space or on Earth. It does not help in seeing around corners.
• A microscope is used to view very small objects. It is not for seeing around corners.
• Fiber optics can be used in periscope - like setups. Light can be transmitted through the fiber optic cable around corners, enabling the user to “see” around corners (by transmitting the light from the other side of the corner to the user's eye).

Answer:

fiber optics
