Physics Revision Questions for Refraction of Light
1. A light ray passes from an optical transparent medium to another as shown in the figure. Which of the following rays CANNOT be a ray of diffraction?
- Ray 1
- Ray 2
- Ray 3
- Ray 4
Correct Answer: B
2. The speed of light in alcohol is 2.21 × 108 m/s. What is the maximum angle for which a light ray emitted by a source inside alcohol leaves the alcohol and moves into air?
- 41.30
- 43.30
- 45.30
- 47.30
Correct Answer: D
3. A light ray is emitted by a source inside alcohol (ca = 221 000 km/s) at 520 to the normal line drawn at the alcohol's surface. Which of the following is TRUE about the angle of refraction?
- The angle of refraction is 520 too, as a total internal reflection does occur
- The angle of refraction is 380
- There is no refraction but we can give an artificial meaning to the angle of refraction by taking the supplementary of the reflection angle, i.e. the angle 1280
- There is no refraction but we can give an artificial meaning to the angle of refraction by taking the supplementary of the reflection angle, i.e. the angle 1420
Correct Answer: D
