Sample questions
-
1.In the given figure, OC = f (focal length of the lens). If rays are drawn from the linear object OO₁, how will the image be formed by the lens?
- A.Real, inverted, and magnified image at 2F.
- B.Virtual image formed at infinity with parallel emergent rays.
- C.Real, erect, and diminished image between F and the lens.
- D.No image formed as rays diverge after refraction.
-
2.A pond appears to be $2.7 \mathrm{~m}$ deep. If the refractive index of water is $4/3$, find the actual depth of the pond.
-

- A.slowed down less and refracted more
- B.slowed down more and refracted less
- C.slowed down less and refracted less
- D.slowed down more and refracted more
-
4.(iii) The angle of incidence on the surface BC is
- A.43°
- B.47°
- C.90°
- D.0°
-
5.Why does the sky appear dark instead of blue to passengers at very high altitudes or to an astronaut?
- A.The atmosphere absorbs all colors of light at high altitudes.
