How do concave lenses differ from convex lenses?

• A. Concave lenses converge light, while convex lenses diverge light
• B. Concave lenses are used for magnification, while convex lenses are not
• C. Concave lenses are thicker at the edges and diverge light rays, while convex lenses are thicker in the center and converge light rays
• D. Concave lenses do not focus light, while convex lenses do

Answer: (C)

Concave lenses and convex lenses have fundamental differences in their structure and behavior with light. Concave lenses are designed to be thinner in the center and thicker at the edges, which causes them to diverge light rays that pass through them. This divergence results in the light rays spreading out, making objects appear smaller or further away. On the other hand, convex lenses are thicker in the center and taper towards the edges, allowing them to converge incoming light rays. When parallel light rays pass through a convex lens, they are brought together to a focal point. This focusing ability can be used for various applications, such as magnification and focusing images. The structural distinction between the two types of lenses directly correlates with their optical behavior: the divergent nature of concave lenses versus the convergent nature of convex lenses. This understanding is crucial in optics, where the design of lenses is tailored to specific functions based on how they manipulate light.
