Practice question

Pick B: 498 nm. Thinking about Sensory System Eye Physiology in a practical way — what the structure does, or what the process achieves — leads you here. Clinically and academically, the same logic shows up again and again: 498 nm is the option that correctly names the structure, process, or principle asked for in Sensory System Eye Physiology. Hence 498 nm is correct. Treat this as a building block for the rest of Sensory System Eye Physiology; neighbouring topics often reuse the same principle. Keep a one-line summary card for this idea and revisit it before the paper; short, repeated review beats long cramming sessions.
