Light Reflection and Refraction | Class 10 Science

Light is electromagnetic radiation within the portion of the electromagnetic spectrum that can be perceived by the human eye. Reflection is the change in direction of a wavefront at an interface between two different media. A curved mirror is a mirror with a curved reflecting surface that is, either convex or concave. The focal length is the distance from the center of the lens to the principal foci of the lens. In this video, we will cover:
1. What is light?
2. What is reflection of light?
3. Laws of reflection of light.
4. Spherical Mirrors
5. Spherical Mirrors: Terminologies
6. Concave vs. Convex
7. Focal length of a spherical mirror
8. Relation between Focal Length & Radius of Curvature
