Light and Formation an Image

The size of an object and its image are the same in this type of mirror...

• Plane

• Convex

• Concave

If the man is 4 m from the mirror, his image is how far from the mirror?

• 2 m

• 4 m

• 8 m

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.

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

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 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

Two big mirrors A and B are fitted side by side on a wall. A man is standing at such a distance from the wall that he can see the erect image of his face in both the mirrors. When the man starts walking towards the mirrors, he finds that the size of his face in mirror A goes on increasing but that in mirror B remains the same:

• Mirror A is concave and mirror B is convex

• Mirror A is plane and mirror B is concave

• Mirror A is concave and mirror B is plane

• Mirror A is convex and mirror B is concave

A mirror with a surface that curves inward like the inside of a bowl

• concave mirror

• convex mirror

• plane mirror

• flat mirror
