A convex lens of focal length 0.10m is used to form a magnified image of an object of height 5mm placed at a distance of 0.08m from the lens. Calculate the position, nature and size of the image.

Calculate the image distance for an object of height 12mm at a distance of 0.20m from a concave lens of focal length 0.30 m, and state the nature and size of the image.

Two lenses A and B have focal lengths of +20cm and, -10cm, respectively.

1. What is the nature of lens A and lens B?
2. What is the power of lens A and lens B?
3. What is the power of combination if lenses A and B are held close together?

A lens of focal length 20cm is used to produce a ten times magnified image of a film slide on a screen. How far must the slide be placed from the lens ?

A man sits in an optician's chair looking into plane mirror which is 2m away from him and views the image of a chart which faces the mirror and is 50cm behind his head. How far away from his eyes does the chart appear to be?

A person got his eyes tested by an optician. The prescription for the spectacle lenses to be made reads:
Left eye: +2.50D, Right eye: +2.00D

1. State whether these lenses are thicker in the middle or at the edges.
2. Which lens bends the light rays more strongly?
3. State whether these spectacle lenses will converge light rays or diverge light rays.

Draw the following diagram, in which a ray of light is incident on a concave/convex mirror, on your answer sheet. Show the path of this ray, after reflection, in each case.

Draw the ray diagram in your answer book and show the formation of image of object AB with suitable rays. Mention the position and nature of image.

Draw the ray diagram and also state the position, relative size and nature of the image formed by a concave mirror when the object is placed between its centre of curvature, C and the focus, F.

An object is placed between infinity and the pole of a convex mirror. Draw a ray diagram and also state the position, the relative size and the nature of the image formed.
