What Is Pitch?
This activity demonstrates that when a series of high-pitched sounds are mixed together, the sound perceived is a low pitch that resembles none of the component tones.
Blind Spot
In this activity you learn to project a stimulus onto the blind spot. Unlike printed blind spot demonstrations, the animated version removes the contribution of eye movements, making the "disappearance" of a target into the blind spot much more impressive.
The Eye
This animation demonstrates the process by which the eye detects light waves.
The Ear
This animation demonstrates the process by which the ear detects sound waves.
