1. What does the law of reflection state?
- A. The angle of incidence is always greater than the angle of reflection
- B. The angle of incidence equals the angle of reflection
- C. The angle of reflection is always 90 degrees
- D. The angle of incidence equals the angle of the surface
2. What is the normal in reflection?
- A. The reflected ray itself
- B. A line perpendicular to the surface at the point of incidence
- C. A line parallel to the mirror's surface
- D. The angle between the incident and reflected rays
3. Which of these correctly describes the image formed by a plane mirror?
- A. Real, inverted, same size
- B. Virtual, upright, laterally inverted
- C. Virtual, inverted, magnified
- D. Real, upright, laterally inverted
4. A ray of light hits a plane mirror at an angle of incidence of 35°. What is the angle of reflection?
- A. 35°
- B. 55°
- C. 70°
- D. 17.5°
5. A student says the image in a mirror could be projected onto a screen if the screen were placed exactly at the image's apparent position behind the mirror. Why is this incorrect?
- A. The image is real, so it can be projected anywhere
- B. The image is virtual — the light rays only appear to come from behind the mirror and never actually meet there, so no screen can capture it
- C. Mirrors do not form images at all
- D. The image only appears at exactly the mirror's surface, not behind it
