Spherical mirrors are mirrors with a spherical reflecting surface. They are classified into two types based on their curvature and the way they reflect light.
- Concave Mirror (Converging Mirror):
- Shape: The reflecting surface is curved inward, resembling a portion of the inside of a sphere. 🌐
- Reflection: Parallel rays of light converge to a focal point after reflecting off the mirror. 🔦
- Applications: Used in applications like shaving mirrors, satellite dishes, telescopes, and headlamps because they focus light. 🚀🔭
- Convex Mirror (Diverging Mirror) 🪞👀:
- Shape: The reflecting surface is curved outward, like the outer surface of a sphere. 🌍
- Reflection: Parallel rays of light diverge after reflection, as though they originated from a focal point behind the mirror. 🌟
- Applications: Commonly used for safety and surveillance (e.g., in vehicle side mirrors, shop surveillance) because they provide a wider field of view and make objects appear smaller. 🚗👁️🗨️
These two types differ in their focal points and how they direct light, making them suitable for different purposes.
