Our perception of the brightness of a color is affected mainly by: the amplitude of light waves.
Night and peripheral vision depend mainly on rods, while daylight and acute vision depend mainly on cones.
The amount of light entering the eye is regulated by changes in the size of the pupil.
If you project a red, a green, and a blue light into space, the point at which the three lights cross will lead to the perception of white light.
eric has been wearing red welding goggles for the past 30 minutes. Based on the opponent-process theory of color vision, when Eric takes off the red goggles, he should expect that objects will temporarily appear to be green.
<span>Cell responses b and c would both occur when cell exposed to the a+b signaling molecules.
The presence of the C signaling molecule will lead to cell response c. Cell response b occurs because the activation of c2 in the C pathway stimulates b1, leading to cell response b. Cell response A remains inactivated because it is inhibited by pathway b activation and its signaling molecule was not present.</span>
