Spherical Mirrors
Mirrors whose reflecting surfaces are spherical.
Concave Mirror
A spherical mirror which has a reflecting surface that curves inwards. Forms a enlarged, diminished, or inverted image depending on distance.
Convex Mirror
A spherical mirror which has a reflecting surface that curves outwards. Forms a diminished, erect image.
First Law of Reflection
The angle of incidence (i) is equal to the angle of reflection (r).
Second Law of Reflection
The incident ray, the normal to the mirror at the point of incidence, and the reflected ray, all lie in the same plane.
Lens
A piece of transparent material, usually made of glass/plastic, which has curved surfaces.
Convex Lens/Converging Lens
Thicker in the middle as compared to the edges. When seen through, it can produce an enlarged, diminished, or inverted image.
Concave lens/Diverging lens
Thicker at the edges as compared to the middle. When seen through, it produces a diminished, erect image.
