Correct answer: B. Convex lens
- A. Concave lens:
- B. Convex lens
- C. Piano convex lens:
- D. Piano concave lens:
Explanation
Explanation: A lens that is thicker at the center and thinner at the edges is called a convex lens.Just to clarify:Convex Lens: A convex lens is thicker at the center and thinner at the edges. It converges light rays, bringing them to a focus. Convex lenses are commonly used in magnifying glasses, camera lenses, and telescopes.Concave Lens: A concave lens is thinner at the center and thicker at the edges. It diverges light rays, causing them to spread out. Concave lenses are often used in corrective eyeglasses for individuals with certain vision issues.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
