Which wavelength corresponds to the red cone type?

Explanation:
Cones in the retina come in three kinds, each tuned to a part of the visible spectrum. The red cone type is the long-wavelength sensor, meaning it responds best to light toward the red end of the spectrum (roughly 560 nm and longer). Short-wavelength cones respond best to blue/violet light, and medium-wavelength cones to green. Since red corresponds to long wavelengths, the wavelength associated with the red cone type is a long-wavelength light.
