Real Image

Q.

The image formed by convex mirrors can always be taken on a screen.

1. True
2. False

Q.

A convex mirror has the largest field of view because

1. It focusses the parallel beam of light at a real point

2. It diverges the parallel beam of light

3. It has a virtual focal point

4. It only forms real images

Q.

An object is kept at a distance of 10 cm from a concave mirror of focal length 5 cm, the magnitude of the image is

1. Less than 10 cm

2. More than 10 cm

3. Equal to 10 cm

4. Can’t calculate with the given data

Q.

According to the sign convention used in ray optics, the origin for object distance measurement is

1. radius of curvature

2. point of focus

3. from infinity

4. from the pole of the mirror

Q.

If a parallel beam of light is incident on a plane mirror, the reflected rays will be

1. Focused at a point

2. Parallel

3. Neither a) nor b)

4. Depends on the medium the mirror is kept

Q. Statement I : Rays incident on a convex mirror from a point source of light, after reflection diverge.
Statement II : A convex mirror can never form a real image for a point source of light.

1. Both the statements are correct and Statement II infers from Statement I
2. Both the statements are correct but Statement II doesn’t infers from Statement I
3. Statement I is correct but Statement II is incorrect
4. Statement I is incorrect and Statement II is correct

Q.

We get a real image when light rays, after reflection,

1. meet at a real point

2. meet at a virtual point

3. don’t meet anywhere

4. diverge in different directions

Q.

A curved mirror converges a parallel beam of light incident on it to its focus, the mirror is

1. parabolic

2. concave

3. convex

4. plane mirror

Q.

As the object moves towards a concave mirror from infinity, the image will

1. keep getting enlarged

2. keep getting diminished

3. keep getting blurred

4. move towards the mirror
