Curved reflectors
Curved mirror are part of spherical surfaces.
There are two type
1.concave or converging mirrors
2.convex or diverging mirrors
The mirror is part of a sphere of centre c known as the centre of curvature of mirror.
The middle point p of the mirror is know as the pole of the mirror.
The mirror is symmetrical about the line pc which is called the principal axis. the radius of the sphere of wish the mirror is part i.e.
R and is known as the radius of curvature.
The wind of the mirror st is know as the aperature.
