A figure divided into squaes each of size `1 mm^2` is being viewed at a distance of 9 cm through magnifying lens of focal lengh 10 cm, held close to the eye.
Draw the ray diagram showing the formation for the image.

A card sheet divided into squares each of size 1 mm^2 is being viewed at a distance of 9 cm through a magnifying glass (a converging lens focal length 10 cm) held close to the eye. What is the magnification produced by the lens? How much is the area of each square in the virtual image?

A card sheet divided into squares each of size 1 mm^2 is being viewed at a distance of 9 cm through a magnifying glass (a converging lens of focal length 9 cm) held close to the eye. What is the angular magnification (magnifying power) of the lens?

A card sheet divided into squares each of size 1 mm^2 is being viewed at a distance of 9 cm through a magnifying glass (a converging lens of focal length 10 cm) held close to the eye. What should be the distance between the object in converging lens and the magnifying glass if the virtual image of each square in the figure is to have an area of 6.25 mm^2 . Would you be able to see the squares distinctly with your eyes very close to the magnifier ?

A wire mesh consisting of very small squares is viewed at a distacne of 8 cm through a mangifying converging lens of focal length 10 cm,ekpt clse to the eye.The mangification produced by the lens is

At what distance should the converging lens of focal length 10 cm be held in order to view the squares distinctly with the maximum possible magnifying power?

An object of size 10 cm is placed at distance of 20 cm in front of aconcave lens of focal length 20 cm. Find the size and nature of image. Also find distance of image from the lens

An object 5 cm in length is held 25cm away from a converging lens of focal length 10 cm. Draw the ray diagram and find the position, size and the nature of image formed

An object is placed at a distance 5 cm from a convex lens of focal lenth 10 cm.Calculate the position nd magnifiation of the image.

A convex lens of focal lenght 20 cm is placed coaxially with a concave mirror of focal length 10 cm at a distance of 50 cm apart from each other.A beam of ligh coming parallel to the principal axis is incident on the convex lens.Find the position diagram showing the formation of the imge.
