FAQs on Spherical Mirrors (Concave and Convex) Basic Terminology Video Lecture - Class 10

1. What are spherical mirrors?
Ans. Spherical mirrors are curved mirrors that have a spherical shape. They can either be concave or convex depending on the curvature of the mirror surface.
2. What is the difference between concave and convex mirrors?
Ans. The main difference between concave and convex mirrors is the way they reflect light. Concave mirrors converge light rays, bringing them together at a focal point, while convex mirrors diverge light rays, spreading them out.
3. How are concave mirrors used in daily life?
Ans. Concave mirrors are commonly used in various applications. They are used in car headlights to focus light and increase visibility, in makeup mirrors to magnify the reflection, and in telescopes to gather and focus light from distant objects.
4. How do convex mirrors affect the size of the reflected image?
Ans. Convex mirrors always produce virtual and diminished images. The image formed by a convex mirror appears smaller than the actual object because the reflected rays diverge and do not converge at a focal point.
5. What is the focal length of a concave mirror?
Ans. The focal length of a concave mirror is the distance between the mirror's surface and its focal point. It is a measure of how strongly the mirror converges light rays. The focal length can be positive or negative depending on the mirror's curvature.
