Derive lens maker's formula for a thin convex lens.

Derive lens maker's formula for a thin concave lens.

(a) Derive lens maker's formula for a biconvex lens. (b) A point object is placed at a distance of 12 cm on the principal axis of a convex lens of focal length 10 cm. A convex mirror is placed coaxially on the other side of the lens at a distance of 10 cm. If the final image coincides with the object, sketch the ray diagram and find the focal length of the convex mirror.

With the help of suitable diagram, sign conventions and assumptions, derive lens Maker's formula for a convex lens.
