When an object is placed at a distance of 60 cm from a convex spherical mirror, the magnification produced is `1//2` .Where should the object be placed to get a magnification of `1//3`?

An object is placed at a distance of f//2 from a convex lens .The image will be

When an object is placed beyond centre of curvature of a concave mirror, the image is formed:

An object is placed at a distance of 1.5 m from a screen and a convex lens is interosed between them .the magnification produced is 4.What is the focal length of the lens?

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.

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

An object 2 cm high is placed at a distance of 5 cm from a concave mirror,whose radius of curvature is 20 cm.Find the position of the image.

An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image

An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image

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.
