Answer 1

Answer:

ANSWER

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.
