## Which has more power thick or thin convex lens?

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. … Hence, the lens with a shorter focal length will have more power or higher refraction (causes more bending of light rays).

## Is a concave lens thicker or thinner?

A concave lens is thicker at the edges than it is in the middle. This causes rays of light to diverge. The light forms a virtual image that is right-side up and smaller than the object.

## Is concave 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 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.

## 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.

## Which convex lens has more focal length?

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.

## Where is convex lens used?

Convex lenses are used in microscopes, magnifying glasses and eyeglasses. They are also used in the cameras to create real images of objects present at a distance.

## Why does a concave lens make things look smaller?

A concave lens is thinner in the middle and broader at the ends. The concave lens diverges or bends the refracted rays outwards because of its shape. These rays never meet to form the image.

## Is a real image always upright?

Real images are always located behind the mirror. Real images can be either upright or inverted. Real images can be magnified in size, reduced in size or the same size as the object. Real images can be formed by concave, convex and plane mirrors.

## Are convex lenses thicker?

A single piece of glass that curves outward and converges the light incident on it is also called a convex lens. They are both thicker in middle than near the edges.

## Which lens is thin at age?

A concave lens is thin in the middle and thick at the edges, so it seems to “cave” inwards. It makes light rays bend outwards, or diverge.

## 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.

## Is power of convex lens positive?

Additional Information: Power of convex lens is positive as it converges the light rays incident on it. Convex lens is also referred to as a converging lens.
