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 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 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?

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? What is the magnification in this case?

A concave lens has focal length of 15 cm. At what distance should the object from the lens be placed so that it forms an image at 10 cm from the lens? Also find the magnification produced by the lens.

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? Is the magnification equal to the magnifying power in this case? Explain.

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
