Althoughsound travels as a wave, the individual particles of the medium do not travel with the wave, but only vibrate back and forth centered on a spot called its equilibrium position, as shown below. Sound is a longitudinal wave. Red dots and arrows illustrate individual particle motion. Can...

The results indicate that a wave number is equal to the wave's frequency divided by its velocity. The velocity used in these formulas will depend on the type of wave and environment in which it travels. For example, the speed of light in free space (vacuum) is approximately 2.99792 × 10...
M: Boy, news travels fast around here! I only got the orders a couple of hours ago. Rachel doesn’t even know… W: Oh, no? So, what are you waiting for? When do you plan to tell her? M: Well, she is at work at the moment. She doesn’t finish until 5. I’ll have to ...
The amplitude of a wave is the distance between its highest point and the point of equilibrium. This highest point is called the antinode. In most waves, the antinode appears to move along the length of the medium. With a standing wave, the antinode remains in the same place, because the...
The wavelength of a wave is given in terms of length, or distance. Usually, it defines the distance between two consecutive peaks of a wave. Here, the peaks of waves can be defined as troughs or crests. The SI unit of meter (m) is used as ...
