  • If lens is thicker then the focal length of it will be shorter or longer?

If lens is thicker then the focal length of it will be shorter or longer?

Answers (1)

The focal length of a lens depends on the curvature of each surface. The more highly curved the surfaces, the shorter the focal length. 
Therefore, a thick lens has shorter focal length than a thin lens.
Hence, The focal length of a thin convex lens is more than that of a thick convex lens.
