The photopigment with a peak absorption at 530 nm is found in which cone type?

Explanation:
Cones come in three kinds, each with a photopigment tuned to a different part of the spectrum. A peak around 530 nm means the pigment responds most strongly to green light, which is characteristic of the medium-wavelength cones. The other cone types peak at shorter (blue) or longer (red) wavelengths, so they’re not best matched to 530 nm. Rods aren’t responsible for color under normal lighting and have a different peak sensitivity. So, the photopigment with a 530 nm peak is found in the medium-wavelength (M-cone) type.
