Best answer: Which has more power a thick convex lens?

Which has more power thick lens or thin lens?

A thicker lens will be having more power because of the focal length of the thicker lens will be less as compared to the thin lens.

Which lens is more powerful or?

If a lens has a shorter focal length it is said to be more powerful. The power of a lens is defined as the reciprocal of the focal length. Lens power is measured in dioptres (D). Converging (convex ) lenses have positive focal lengths, so they also have positive power values.

Why are thick lenses more powerful?

A lens with more “bending power” has a shorter focal length, because it alters the path of the light rays more effectively than a weaker lens. … But for thicker lenses, how thick they are does make a difference, and in general, results in a shorter focal length.

Which has more power a thick?

A thick convex lens has more power than a thin one because it has greater curvature or lesser focal length than a thin lens.

Is concave lens thick or thin?

A concave lens is shaped like two half moons back to back, thin at the center and thick at the edges. Concave lenses are diverging lenses. Diverging lenses force light rays to bend away and never come together to a point.

Which convex lens has more focal length thick or thin?

A thick convex lens has more power than a thin convex lens because it has greater curvature or lesser focal length than a thin lens. A thick convex lens has greater curvature or lesser focal length, whereas a thin convex lens has lesser curvature or greater focal length.

Which converging lens has the greatest power?

The convex lens of smaller focal length (= 20 cm) has greater power since focal length is reciprocal of power.

What is the difference between one lens and another that is more powerful than it?

Such a lens is called a converging (or convex) lens for the converging effect it has on light rays. … The greater effect a lens has on light rays, the more powerful it is said to be. A powerful converging lens will focus parallel light rays closer to itself and will have a smaller focal length than a weak lens.

What is thick lens?

(noun) Lenses whose thicknesses are not negligible (i.e., one cannot make the simple assumption that a light ray is refracted only once in the lens).
