Describe how vision works according to an extramission theory and describe why such a theory is wrong. Extramission theory states that vision works by your eyes emitting rays. Such a theory is wrong because we cannot see with the absence of light. Receiving the stimulus and encoding it into the brain. Explain what the task is the visual system. The task of the visual system is to transduce light into neural impulses so the brain can understand electromagnetic energy. Explain how the visual system accomplishes its task, using the words "light," "lens," "retina," "rods," "cones," "optic nerve," in that order. First light inters through the pupil, in which the lens focuses the light to the retina, which contains photoreceptor cells, this information goes into the optic nerve. Explain what the difference is between sensation and perception. Sensation is the information you get first hand and perception is interpreting that information after its been encoded.
