![]() We will look at wavelength, frequency, period, and amplitude. Below we will explore different wave characteristics. These two opposing forces cause the wave. The inertial property of the medium, a medium’s natural tendency not to change, is fighting the restorative property. This is called the restorative property of the medium. The compressed molecules desperately want to get back to their original state so they push upward. ![]() The molecules situated at the top of the table are compressing against molecules underneath them. As the hammer crashes, the table molecules are now out of equilibrium. The hammer crashed into the table causing the table molecules to compress. Let’s look at what is happing on the molecular level. The hammer hitting the table causes the disturbance which ultimately causes the sound wave. This is what is happening when you drop the hammer on the table. The waves that propagate from the shot put’s entry into pool are independent of that event. The shot put breeches the water and sinks to the bottom of the pool. Visualize yourself heaving a shot put into your backyard pool. ![]() What does that exactly mean? Here we are dealing with two independent events: first, the hammer hitting the table causing a disturbance second, the wave propagating or moving away from the disturbance. What happened? The hammer hitting the table created a disturbance in the medium causing a wave to propagate through the medium. As the hammer hits the table, you hear a loud noise. Close your eyes and picture dropping a hammer onto a table. What is a sound wave? Not being able to see a sound wave makes this a difficult question.
