Plane Mirror Imaging - Quiz - Quiz Questions
Test your understanding of plane mirror imaging laws, virtual image properties, symmetry principles, and object-image distance relationships in reflections.
2. When the candle moves 5cm towards the plane mirror, the size of the image will:
- A. Become larger
- B. Become smaller
- C. Remain unchanged
- D. First become larger then smaller
3. In the ray diagram of plane mirror imaging, the image formed by the intersection of the backward extensions of reflected rays is:
- A. Real image
- B. Virtual image
- C. Inverted image
- D. Magnified image
4. If you walk vertically towards a plane mirror at a speed of $1 m/s$, your image's speed relative to you is:
- A. $1 m/s$
- B. $0.5 m/s$
- C. $2 m/s$
- D. $0 m/s$
5. To see your full-body image in a plane mirror on the wall, the length of the mirror must be at least:
- A. Same height
- B. Half
- C. One-third
- D. One-quarter
6. A person with a height of $1.6m$ stands $2m$ in front of a plane mirror. How far is his image from him?
- A. $2m$
- B. $3.2m$
- C. $4m$
- D. $1.6m$
7. A beam of light hits a plane mirror perpendicularly. If the direction of the incident ray remains unchanged and the plane mirror is rotated by an angle $\theta$, the angle rotated by the reflected ray is:
- A. $\theta$
- B. $2\theta$
- C. $\theta / 2$
- D. $0$
8. Why do precision optical instruments typically use "First Surface Mirrors" instead of ordinary back-silvered glass mirrors?
- A. For better aesthetics
- B. To prevent ghosting
- C. For better wear resistance
- D. To save costs
9. When a person stands in front of a plane mirror and moves backward, the size of his image in the mirror:
- A. Becomes larger
- B. Becomes smaller
- C. Remains unchanged
- D. First becomes smaller then larger
10. True or False: A virtual image formed by a plane mirror can also be captured by a camera.
- True
- False
