2.  A ray of light that strikes a plane mirror PQ at an angle of incidence of 30o, is reflected from the plane mirror and then strikes a second plane mirror QR placed at right angles to the first mirror. The angle of reflection at the second mirror is:

3. An object is placed at 100 mm in front of a concave mirror which produces an upright image (erect image). The radius of curvature of the mirror is:

4. Which position of the object will produce a magnified virtual image, if a concave mirror of focal length 15 cm is being used?

5. A concave mirror produces a magnification of +4. The object is placed:

6. 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:

7. A ray of light is travelling in a direction perpendicular to the boundary of a parallel glass slab. The ray of light:

8. A lens of focal length 12 cm forms an erect image, three times the size of the object. The distance between the object and image is:

9. If an object is placed 21 cm from a converging lens, the image formed is slightly
smaller than the object. If the object is placed at a distance of 19 cm from the lens,
the image formed is slightly larger than the object. The approximate focal length of
the lens is:
