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

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 $+ 4D$.
