Show how physical properties of light waves are associated with perceptual experience. Visual and auditory stimuli both occur in the form of waves. Although the two stimuli are very different in terms of composition, wave forms share similar characteristics that are especially important to our visual and auditory perceptions.
The amplitude of light waves is associated with our experience of brightness or intensity of color, with larger amplitudes appearing brighter. Different wavelengths of light are associated with our perception of different colors.

If light is a particle, then why does it refract when travelling from one medium to another? And if light is a wave, then why does it dislodge electrons ? But all behavior of light can be explained by combining the two models: light behaves like particles and light behaves like waves.
In the visual system, a light wave’s wavelength is generally associated with color, and its amplitude is associated with brightness. In the auditory system, a sound’s frequency is associated with pitch, and its amplitude is associated with loudness.

Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Yet there is still more reason to believe in the wavelike nature of light. Continue with Lesson 1 to learn about more behaviors that could never be explained by a strictly particle-view of light.
