## Chapter 13: Vibration and Waves

 What is Hooke's law and why is it so important? What is simple harmonic motion? What happens to the energy of a mass on a spring as it undergoes simple harmonic motion? Show that the potential energy of a mass on a spring depends upon the square of its distance from equilibrium. What are the quantities necessary for describing simple harmonic motion? What does the period of a simple pendulum depend upon? How is a physical pendulum different from a simple pendulum? How is the motion of a traveling wave related to simple harmonic motion? What quantities used for the description of a mass on a spring are also applicable to a traveling wave on a string? What is the relationship between frequency, wavelength and velocity for a traveling wave? What is meant by transverse and longitudinal waves? What determines the speed of a wave in a stretched string? Is the speed of a wave in a string dependent upon the frequency of the wave? the amplitude?

## Chapter 14: Sound Waves

 Describe what happens when a sound wave travels through air. What conditions must be met for it to be audible? What determines the speed of sound in air? Describe the four wave phenomena: reflection, interference, refraction, diffraction . Are they all observed with sound waves? Describe the superposition of waves and its relationship to wave interference. Describe the change of phase of a string wave when it reflects off a fixed end. How does that affect interference of the incident and reflected waves? What is meant by a resonant frequency? How is the resonant frequency determined for a stretched string? Describe the resonances or "standing waves" of open and closed cylindrical pipes. *Periodic motion *Elasticity *Traveling waves *Audible sound *Wave relationship *Reflection *Refraction *Interference *Diffraction *Wave speed *Speed of sound in air *Beats *Subjective tones *State Patrol radar *Heterodyne principle *AM radio *FM radio *Pitch *Loudness *Quality *Longitudinal waves *Transverse waves *Mammoth Lakes example *Sound waves in air *Pitch *Ear *Place theory *Sharpening *Loudness *Sound intensity *Decibels *Quality *Resonance *Standing waves *Vibrating string *Air columns *Open air column *Closed air column *Cavity resonance *Coke bottle *Bass reflex speaker
