What is magnification?

What is th magnification produced by a single convex lens used as simple microscope in normal use?

Define magnification of spherical mirror. What is the magnification produced in a plane mirror?

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 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?

What is linear magnification? Write its expression for a convex lens.

What is simple microscope? Find an expression for its magnification.

The focal lengths of the objective and eye-piece of a compound microscope are 4 cm and 6 cm respectively. If an object is placed at a distance of 6 cm from the objective, what is the magnification produced by the microscope? Distance of distinct vision = 25 cm.

A mirror has magnification 0.4, What type of the mirror is and what type of the image is formed?

A compound microscope has a magnification of 30. The focal length of its eye-piece is 5 cm. Assuming the final image to be formed at least distance of distinct vision (25 cm),calculate the magnification produced by the objective.
