Effect of Concave Mirrors on Parallel Light Rays
When parallel light rays strike a concave mirror, they exhibit a specific behavior due to the mirror's shape.
Understanding Concave Mirrors
- A concave mirror is curved inward, resembling a bowl.
- It has a focal point (F) where light rays converge after reflection.
Behavior of Parallel Light Rays
- When parallel light rays (such as those from a distant source) hit the concave surface, they reflect inward.
Convergence of Light Rays
- These rays do not remain unchanged or diverge; instead, they converge at the focal point.
- This convergence creates a real image if the object is placed beyond the focal length.
Applications of Concave Mirrors
- Used in telescopes, headlights, and shaving mirrors to focus light and enhance visibility.
- The ability to converge light enhances their utility in various optical devices.
In summary, a concave mirror causes parallel light rays to converge at a point, making option 'D' the correct answer.

A concave mirror causes parallel light rays to converge, focusing them to a single point. This property is utilized in applications such as telescopes and solar concentrators.
