A person with normal near point (=25 cm) reads a book using magnifying glass of focal length 5 cm. What is the farthest distance at which he can read the book through the magnifying glass?

A man with normal near point (25 cm) reads a book with small print using a magnifying glass: a thin convex lens of focal length 5 cm- What is the closest and the farthest distance at which he should keep the lens from the page so that he can read the book when viewing through the magnifying glass?

A man with normal near point (25 cm) reads a book with small print using a magnifying glass: a thin convex lens of focal length 5 cm- What is the maximum and the minimum angular magnification (magnifying power) possible using the above simple microscope?

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 ?

Calculate the maximum angular magnification produced by a mangifying glass of 5 cm focal length .Distance fo distinct vision =25 cm.

A person with a normal near point (25 cm) using a compound microscope with objective of focal length 8.0 mm and an eyepiece of focal length 2.5cm can bring an object placed at 9.0mm from the objective in sharp focus. What is the separation between the two lenses? Calculate the magnifying power of the microscope.

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?

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 is at a distance of 5 m from a convex mirror of focal length 10 cm.Where is he image formed ?
