Question
- A. They only show the lens without the retina.
- B. They illustrate how light is refracted by the lens.
- C. They do not include the eye structure.
- D. They only apply to hyperopia.
Answer
The correct option is They illustrate how light is refracted by the lens.. This answer is correct because it matches the approved learning objective to interpret ray diagrams showing myopia, hyperopia and their correction in the subtopic The eye (biology only).
Explanation
The correct option is They illustrate how light is refracted by the lens.. They illustrate how light is refracted by the lens. is correct because it directly supports the approved learning objective to interpret ray diagrams showing myopia, hyperopia and their correction. This belongs to the subtopic The eye (biology only) within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The eye (biology only).
Common mistake
Misinterpreting Ray Diagrams
Students often confuse the positions of the lens and the retina in ray diagrams, leading to incorrect conclusions about myopia and hyperopia.
Carefully label each part of the ray diagram, ensuring the lens and retina are correctly positioned. Review the definitions of myopia and hyperopia to understand how light focuses relative to the retina.
