MCQ Answer Key
| Q.No. | Answer | Explanation |
|---|---|---|
| 1 | A | Speed in water = speed in vacuum / refractive index. |
| 2 | C | Law of reflection: angle of incidence = angle of reflection. |
| 3 | B | Plane mirrors form virtual, laterally inverted images. |
| 4 | A | Use lens formula and solve for object distance. |
| 5 | B | Bending of light at water surface is refraction. |
| 6 | B | Critical angle = sin-1(1/1.5) ≈ 41.8°. |
| 7 | B | Only interference demonstrates wave nature of light. |
| 8 | D | Mirages result from total internal reflection in air layers. |
| 9 | B | At center of curvature: real, inverted, same size image. |
| 10 | A | Concave lens corrects myopia (short-sightedness). |
| 11 | B | Violet bends most due to smallest wavelength. |
| 12 | C | Power P=1/f (in meters), so -0.25m ⇒ -4 D. |
| 13 | B | Smaller wavelength means higher resolving power (RP ∝ 1/λ). |
| 14 | B | From denser to rarer, light bends away from normal. |
| 15 | B | Interference in YDSE proves wave nature of light. |
| 16 | B | Convex mirrors yield diminished, erect, and wide images. |
| 17 | D | Light speed is highest in vacuum. |
| 18 | B | Power of a lens is measured in diopters (D). |
| 19 | B | Dispersion: colors have different speeds, bend differently. |
