L cone and S cone; green.
C
L cone and M cone; orange.
D
S cone and M cone; green.
Verified step by step guidance1
Identify the wavelength of light in the problem, which is 610 nm.
Refer to the provided graph to determine which cones are sensitive to this wavelength. Look for the peaks of the L (Long) and M (Medium) cones in the graph.
Notice that the L cone (red line) has a peak sensitivity around 560-580 nm and extends into the 610 nm range, indicating it will be stimulated.
Observe that the M cone (green line) also has a significant response in the 610 nm range, suggesting it will be stimulated as well.
Based on the graph's color spectrum, light at 610 nm falls within the orange range, so the perception will be orange when both L and M cones are stimulated.
