Standing on the seashore, it is somewhat incredible to consider that the waves rolling in may have been generated hundreds of miles away, and yet the water molecules through which the waves travel havent moved very far at all. Ocean waves are just one example of waves, which are defined as disturbances or perturbations that can travel very long distances from their points of origin with little or no net displacement of the medium through which they travel. Our ears are sensitive detectors of sound waves. When we listen to music, or talk to a friend, we respond to the complex patterns of frequency and amplitude inherent in natural sound, and interpret them. Conceptual StrandUnderstanding sound and light is accomplished by investigating wave behavior.Guiding QuestionHow do the properties of mechanical waves, sound, and light explain the behavior of waves?
