Image Formation by Spherical Mirrors

Q.

Choose the ray diagram which shows the image formation?

1. 

2. 

3. 

4. None of these

Q.

Ray of light falling parallel to the principal axis follows which path after reflection?

1. 1

2. 2

3. 3

4. 4

Q.

If we want to form virtual, erect and enlarged image. Then which mirror and position should we choose?

1. concave, centre of curvature

2. convex, between focus point and pole

3. concave, beyond focus point

4. concave, between focus point and pole

Q.

To obtain a real, inverted and highly enlarged image, choose the suitable type of mirror and the position of object in front of it.

1. Type of mirror: Convex mirror,
   Position of object: At focus point

2. Type of mirror: concave mirror,
   Position of object: At focus

3. Type of mirror: concave mirror,
   Position of object: At centre of curvature

4. Type of mirror: concave mirror,
   Position of object: Beyond centre of curvature

Q. Rohit wants to have an erect image of an object using a converging mirror of focal length 40 cm.
(a) Specify the range of distance where the object can be placed in front of the mirror. Justify.
(b) Draw a ray diagram to show image formation in this case.
(c) State one use of the mirror based on the above kind of image formation.

Q. The object position for a concave mirror to cast a real image of the same size as the object is:

1. At infinity
2. At C
3. Between F and C
4. Between P and F

Q.

Where is the image formed?

1. at A point

2. cannot be determined, since we need at least 2 rays to form a image

3. forms at infinity

4. image is formed at pole

Q.

Which of the following mirrors always form a virtual and diminished image irrespective of the object location?

1. concave

2. parabolic concave mirror

3. plane mirror

4. convex mirror

Q.

The radius of curvature of a concave mirror is 10 cm. If I want to capture the image of the sun, at what distance from the pole of the mirror would an image be formed?

1. α

2. 10 cm

3. 5 cm

4. 20 cm

Q.

Match the given cases of image formation with the position of the object:

1. I - d, II - c, III - b, IV - a

2. I - c, II - d, III - b, IV - a

3. I - c, II - d, III - a, IV - b

4. I - b, II - d, III - a, IV - a
