Which convex lens has more focal length thick or thin?

1.	Which convex lens has more focal length thick or thin?
Answer» Thin convex lensesStep by step explanation:For convex LENSES with a big thickness, this means that the light rays travel inside them for a LONGER period of TIME. As a CONSEQUENCE, the the light rays are bent more in the thick convex lenses. As the BENDING of light rays increases, the focal length decreases. Hence, thin convex lenses have a higher focal length.
