Question

Which convex lens has more focal length thick or thin?

Answer 1

Answer:

Thin convex lenses

Step 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.

Answer 2

thin convex lens has more focal length
