Document Summary

Module 18- vision and perceptual organization and interpretation. Eyes receive light energy and transduce (transform) it into neural messages that our brain then processes into what we see. When see red, pulses of electromagnetic energy strike eye that your visual system perceives as red. Visible light is thin slice of the whole spectrum of electromagnetic energy ranging from short gamma waves to long waves of radio transmission. Two physical characteristic of light help determine our sensory experience: Light"s wavelength- the distance from the peak of one light to the peak of the next that determines its hue (the dimension of colour that is determined by the wavelength of light). Electromagnetic wavelengths vary from short blips of cosmic rays to long pulses of radio transmission. Intensity, the amount of energy in a light of sound wave, which we perceive as brightness or loudness, as determined by the wave"s amplitude, influences brightness.
