The length of an object is 5 cm. An image of length 10cm is obtained when it is placed at a distance of 2 cm in front of a convex lens. What is the linear magnification and image distance?

The length of an object is 10 cm. An image of length 20cm is obtained when it is placed at a distance of 2 cm in front of a convex lens. What is the linear magnification and image distance

An object is placed at a distance of 20 cm from a concave mirror of focal lenght 10 cm. What is the image distance?

The focal lengths of the objective and the eyepiece of a compound microscope are 1 cm 5 cm respectively. If an object is placed at a distance of 1.1cm from the objective the final image is formed at a distance of 25 cm from the eyes. Determine the magnification and the distance between the lenses.

If the object and image distance is 30 cm of a convex lense then its focal length is

An object is kept at a far off distance in front of a convex lens of focal length 15 cm. State the position of the image.

A 2.0cm tall object is placed 15cm in front of a concave mirror of focal length 10cm. What is the size and nature of the image?

An object is placed perpendicularly on the principal axis of a concave mirror of focal length 25 cm and an image is formed at a distance of 100 cm in front of the mirror. Determine the position of the object and mangnification of the image.

If an object is placed at a distance of 40 cm from a concave mirror of focal length 20 cm , them the image wil be

Thin converging lenses of focal lengths 2 cm and 10 cm are used respectively as the objective and the eyepiece of a microscope. The distance between the optical centre of the lenses is 26 cm . If an object is placed at a distance of 2.25 cm from the objective , find the position and magnification of the final image.
