Document Summary
Mistakes can occur when we are seated and a moving scene around us makes us feel like we"re moving. We can determine the movement of the object versus the image change due to movement of our own eyes. And a sensory signal is sent from the eye (movement on the back of the eye image retina change) to the comparator when object is moving and changes position on the retina. Stimulus: mechanical energy (sound) energy that occurs when a molecule hits up against another. Pressure wave of molecules pressing up against each other causes movement of the eardrum, message being sent to the inner ear that causes hairs to move back and forth, and you hear sound. Need molecules no sound in space. Speed of sound varies based on the medium in air the molecules are far apart, in water the molecules are close together (faster bc they don"t have to go so far to push against one another)
