Question preview
Three examples from the live 250-question bank. Answers appear after attempting them in practice mode.
Example 1 · difficulty 2/5

- A. 30°
- B. 60°
- C. 45°
- D. 90°
Example 2 · difficulty 3/5

- B. 12 cm in front of the lens, virtual, erect and diminished
- C. 60 cm in front of the lens, virtual, erect and magnified
- D. 12 cm behind the lens, real, inverted and diminished
