## What is the maximum magnifying power of a convex lens of focal length 5 cm?

Correct answer:The magnification of the magnifying glass is **(d) 5**.

## What is the magnifying power of convex lens?

Magnification of Convex Lens:

A magnification of 2 indicates the image is twice the size of the object and **a magnification of 1 indicates an image size being the same** as the object size. If the magnification is positive, then the image is upright compared to the object (virtual image).

## What is the power of a convex lens of focal length 0.5 m?

Thus, a diverging lens having a focal length of 1 m has a power of -1 diopter, and a converging lens of focal length 0.5 m has a power of **two diopters**.

## What is the formula of magnifying power?

**M=1+Df** when the image forms at infinity. Where D is the least distance of distinct vision and is equal to v. D being constant and the magnifying power depends upon the focal length of the lens. Smaller the focal length is going greater will be the magnifying power of the lens.

## What determines the magnification of a lens?

The magnification produced by a lens is defined as **ratio of the height of the image to the height of the object**. It is denoted by “begin{align*}mend{align*}”. The magnification produced by a lens is equal to the ratio of image distance to the object distance.

## What is the greatest magnification obtained with a lens of 10 cm?

Hence, The magnification of convex lens is **3.5**.

## 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.

## What is the difference between magnification and magnifying power?

Magnification – magnification is **equal to the ratio of size of image and size of object**. … Magnifying power – magnifying is equal to the ratio of the dimension of the image and the object. So, magnification gives how many time the image has been magnified by instruments.

## What would be the power of a concave lens of focal length 0.5 m?

In the same way, a power of **-2.0D** means a concave lens of focal length -0.5m.

## What is the power of convex lens of focal length?

The power of a convex lens (converging lens) is **positive as its focal length is positive**. The power of a concave lens (diverging lens) is negative as its focal length is negative. The power of a plane glass plate is 0.

## What is the power of a lens of focal length 25 cm?

In this question it is given that the lens is convex, and its focal length is $25$ cm. First we will convert the focal length in meters. As it is a convex lens so its power is positive. Thus, the power of the lens is **$+ 4D$.**
