4. In Graph D, focus only on the SWS cone. Pay attention to the Normalized sensitivity. Assume that a light of intensity 1.0 illuminates the cone at 440 nm. Again, focusing only on the SWS cone, and recalling that cones sum the various activations they receive, answer: what two frequencies of light at a specic intensity would be required to illuminate the cone so that it gave a response equivalent to that caused in the cone by the single light at 440 at intensity 1.0? (There can be multiple correct answers; justify your specic answer.) What is the implication of this for the relationship between a SWS cone activation and information about the specic wavelength(s) that illuminates the cone? Does cone activation reveal the wavelength of the light causing the activation?
