Question

Long wavelength light would look very bright/dim to a rod monochromat. They would have a more/less steep matching function than a protanope

Answer 1

Rod monochromats have rods as their only functioning photoreceptors and can sense light about 1000 times dimmer than cones. Long wavelength light would look dim to a rod monochromat and they would have a less steep matching function than a protanope.

Step-by-step explanation:

Rod monochromats are individuals who lack functioning cone photoreceptor cells and have rods as their only functional photoreceptors. Rods are sensitive to light in low light conditions and can sense light about 1000 times dimmer than cones. Long wavelength light, such as red light, would look dim to a rod monochromat because rods are less sensitive to longer wavelengths. They would have a less steep matching function compared to a protanope, who lacks functioning red cone cells, because rods have a broader sensitivity range than cones.
