Peak Wavelength Sensitivity of Cone Pigments
The three types of photopigments in retinal cones have distinct peak sensitivities to different wavelengths of light. The pigment in short-wavelength (S) cones, which corresponds to blue perception, is most sensitive at approximately 455 nm. The pigment in medium-wavelength (M) cones (green) peaks at about 535 nm, and the pigment in long-wavelength (L) cones (red) has a peak sensitivity around 580 nm.

A light source emits a pure, single wavelength of 560 nm. The human retina contains three types of color-sensitive cells, with peak sensitivities at approximately 455 nm (short-wavelength), 535 nm (medium-wavelength), and 580 nm (long-wavelength). Based on this information, which statement best describes how these cells would respond to the 560 nm light?
