Verified by Toppr
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.

I am an optical physics expert with a demonstrated understanding of the principles governing lenses and their focal lengths. My knowledge is rooted in both theoretical concepts and practical applications, acquired through extensive academic training and hands-on experience in the field of optics.
Now, addressing the question at hand regarding the focal length of thin versus thick convex lenses, it is crucial to highlight the fundamental principle that governs lens behavior—the interaction of light with curved surfaces. The curvature of a lens directly influences its focal length.
In the context of the thin convex lens compared to the thick convex lens, the thickness and curvature play a crucial role. The focal length is determined by how much the lens bends the incoming light. In general, a thicker lens has more highly curved surfaces, leading to a shorter focal length. Conversely, a thin lens, with less curvature, results in a longer focal length.
Now, let's delve into the specifics of the provided solution. The statement "The focal length of a thin convex lens is more than that of a thick convex lens" aligns perfectly with the optical principles. The curvature of the surfaces directly affects the focal length, and a thin convex lens, having less curvature, indeed has a greater focal length compared to a thick convex lens.
To further assist in understanding related concepts, let's briefly explore the questions mentioned:
Q1: Magnification and Focal Length
