A periscope enables visibility of objects that are not directly in sight by employing two plane mirrors arranged at angles to reflect light from the objects to the viewer's eyes. This arrangement allows one to see over obstacles or around corners.

Understanding the Periscope
A periscope is an optical instrument that enables observation of objects that are not in the direct line of sight. This is particularly useful in various applications, including submarines and trench warfare.
How It Works
- A periscope typically comprises two plane mirrors positioned at a 45-degree angle to the line of sight.
- The top mirror reflects light from an object down into the periscope tube, while the bottom mirror reflects this light horizontally to the observer's eye.
Key Components
- Two Plane Mirrors:
- The use of two mirrors is crucial. They redirect the light path, allowing the viewer to see objects that are otherwise obstructed.
- Angle of Reflection:
- The mirrors are angled so that the light can change direction effectively. This manipulation of light allows a person to see around corners or over obstacles.
Advantages of Using a Periscope
- Stealth Observation:
- Helps in maintaining a low profile, especially in military applications.
- Wide Range of View:
- Enables visibility from a high position without being exposed.
Conclusion
In summary, the correct answer is option 'C' because a periscope employs two plane mirrors to redirect light, allowing one to see objects that are not in direct view. This ingenious design effectively utilizes the principles of reflection, making it a simple yet powerful optical tool.
