| 7828971778 | Wavelength | The distance from the peak of one light or sound wave to the next peak. |  | 0 |
| 7828971779 | Hue | The dimension of color that is determined by the wavelength of light. | 1 | |
| 7828971780 | Intensity | The more energy, the more intensity a wave has. More intensity = brighter color. | 2 | |
| 7828971781 | Pupil | The adjustable opening in the center of the eye through which light enters. |  | 3 |
| 7828971782 | Iris | A Ring of muscle tissue that forms the colors portion of the eye around the pupil. Also controls the size of the pupil opening. | 4 | |
| 7828971783 | Lens | The transparent structure behind the pupil that changes shape to help focus images on the retina | 5 | |
| 7828971784 | Retina | Light sensitive inner surface of the eye, containing receptor rods and cones along with layers of neurons that begin the process of visual information | 6 | |
| 7828971785 | Accomadation | The process by which the eye's lens changes shape to focus near or far objects on the retina | 7 | |
| 7828971786 | Rods | Retinal receptors able to detect black, white and gray; used for peripheral and twilight vision when cones don't respond | 8 | |
| 7828971787 | Cones | Retinal receptor cells concentrated near the center of the retina and that function in well lit conditions. They detect fine detail and give rise to color sensations | 9 | |
| 7828971788 | Optic Nerve | The nerve that carries neural impulses from the eye to the brain. | 10 | |
| 7828971789 | Blind Spot | The point at which the optic nerve leaves the eye, creating a blind spot because no receptor cells are located there. | 11 | |
| 7828971790 | Fovea | The central focal point in the retina where cones are heavily concentrated | 12 | |
| 7828971791 | Feature Detectors | Nerve cells in the brain that respond to specific features of the stimulus, such as shape, angle, or movement | 13 | |
| 7828971792 | Parallel Processing | The processing of several aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision. | 14 | |
| 7828971793 | Young-Helmholtz Trichromatic Theory | the retina contains three different color receptors - one most sensitive to red, one to green, one to blue - which, when stimulated in combination, can produce the perception of any color. | 15 | |
| 7828971794 | Opponent Process Theory | The theory that opposing retinal processes enable color vision. For example, some cells are stimulated by green and inhibited by red; others are stimulated by red and inhibited by green white-black red-green yellow-blue | 16 |
