 Explain how different sounds are modeled, described, and produced.  Design ways to determine the speed, frequency, period and wavelength of a sound wave model. Procedure: Go to https://phet.colorado.edu/en/simulation/legacy/sound and “Run” the program. 1. Use the Listen to a Single Source tab in Sound Waves to start your investigation of sound. Turn on the Audio Enabled so you can hear the sound.  When you change the frequency, how does the sound change? How does the visual model change? When the frequency is increased, the wave lengths become shorter and faster. The pitch of sound is higher wh
