Energy
|
Sound waves are generated from mechanical oscillations of objects and travel through a medium.
|
9P.2.3.1.1 Analyze the frequency, period and amplitude of an oscillatory system. 9P.2.3.1.3 Explain how interference, resonance, refraction and reflection affect sound waves. 9.2.3.2.3 Describe how energy is transferred through sound waves and how pitch and loudness are related to wave properties of frequency and amplitude
