Document Summary

Transduction: conversion of one form of energy into another. In sensation, the transforming of stimulus energies, such as sights, sounds, and smells, into neural impulses our brains can interpret. Wavelength: the distance from the peak of one light or sound wave to the peak of the next. Electromagnetic versions of this vary from the short blips of cosmic rays to the long pulses of radio transmission. Hue: the dimension of color that is determined by the wavelength of light; what we know as the color names blue, green, and so forth. Intensity: the amount of energy in a light or sound wave, which we perceive as brightness or loudness, as determined by the wave"s amplitude. Pupil: the adjustable opening in the center of the eye through which light enters. Iris: a ring of muscle tissue that forms the colored portion of the eye around the pupil and controls the size of the pupil opening.
