The bouncing back of rays of light from a polished and shiny surface is called reflection of light.
Types of Mirror
- Plain Mirror
Spherical/ Curved Mirror
(a) Concave Mirror: With reflecting surface curved inward
(b) Convex Mirror: With reflecting surface curved outward
Types of Images
- Real Image
- Virtual Image
Laws of Reflection of light
- The angle of incidence and angle of reflection is equal.
- The incident ray, reflected ray and normal to the point of reflection lie in the same plane.
- Pole:The center of reflecting surface of a spherical mirror
- Center Of Curvature:The center of sphere; of which the reflecting surface of a spherical mirror is a part.
- Radius Of Curvature:The radius of sphere; of which the reflecting surface of a spherical mirror is a part.
- Principal Axis: Imaginary line passing through the center of curvature and pole of a spherical mirror
- Principal Focus: Point on principal axis at which parallel rays; coming from infinity; converge after reflection
After going through these important points, go through the videos and discussion in the Eckovation app.
