Question

Which of the following statements is true? A meniscus lens is converging if the convex surface has the same radius as the concave surface. A meniscus lens is diverging if the convex surface has the same radius as the concave surface. A meniscus lens is converging if the convex surface has a smaller radius than the concave surface. A meniscus lens is converging if the convex surface has a larger radius than the concave surface.

Answer 1

True: A meniscus lens is converging if the convex surface has a larger radius than the concave surface.

Step-by-step explanation:

A converging lens is one whose thickness decreases from the center towards the edges so that when light rays from objects pass through, they join in parallel, that is, they converge, at a single point or main axis.

As for divergent lenses, their composition is just the opposite of convergent lenses; they have a greater thickness at the edges, which gradually decreases towards the center and, as a consequence, their effect on light is also different: instead of doing it joining in parallel, as they do in converging, the reflected rays separate by going through the lens
