Light and Formation an Image

An object is placed at a concave mirror's center of curvature. The image produced by the mirror is located

• out beyond the center of curvature.
• at the center of curvature.
• between the center of curvature and the focal point.
• at the focal point.

An object is positioned between a concave mirror's center of curvature and its focal point. The image produced by the mirror is located

• beyond the center of curvature.

• at the center of curvature.

• between the center of curvature and the focal point.

• at the focal point.

An object is situated between a concave mirror's surface and its focal point. The image formed in this case is

• real and inverted.
• real and erect.
• virtual and erect.
• virtual and inverted

Concave spherical mirrors produce images which

• are always smaller than the actual object.
• are always larger than the actual object.
• are always the same size as the actual object.
• could be smaller than, larger than, or the same size as the actual object, depending on the placement of the object.

A person kept an object at beyond 'C' of a concave mirror. Where should a screen be kept if he needs to project the image on it?

• At F

• At C

• Between F and P

• Between C and F

A candle is kept between F and P of a concave mirror. Can this image be projected on a screen?

• Yes it can be

• No it cannot be

• Cannot be predicted

At which position of the object, will a concave mirror produces magnified and erect image?

• At C

• Between F and P

• Between C and F

• At F

If you wish to get enlarged image of any object, which mirror will u select?

• Convex mirror

• Plane mirror

• None of these

• Concave mirror

How to you decide that a mirror is concave or convex without touching it?

• By observing the surface

• By keeping them in sunlight so that surfaces can be clearly seen

• By keeping them in front of your face and observing the kind of image we obtain

• By moving mirrors here and there

A point object is placed at a distance of 20 cm from a convex mirror of focal length 20 cm. The image will form at:

• at infinity

• at focus

• at the pole

• behind the mirror
