Speed of Sound
Learning Objectives By the end of this section, you will be able to: Sound, like all waves, travels at a certain speed and has the properties of frequency and wavelength. You can observe direct evidence of the speed of sound…

Sound Waves
Learning Objectives By the end of this section, you will be able to: The physical phenomenon of sound is a disturbance of matter that is transmitted from its source outward. Hearing is the perception of sound, just as seeing is the perception of visible…
Introduction
Figure 17.1 Hearing is an important human sense that can detect frequencies of sound, ranging between 20 Hz and 20 kHz. However, other species have very different ranges of hearing. Bats, for example, emit clicks in ultrasound, using frequencies beyond 20 kHz.…

Standing Waves and Resonance
Learning Objectives By the end of this section, you will be able to: Throughout this chapter, we have been studying traveling waves, or waves that transport energy from one place to another. Under certain conditions, waves can bounce back and…
Interference of Waves
Learning Objectives By the end of this section, you will be able to: Up to now, we have been studying mechanical waves that propagate continuously through a medium, but we have not discussed what happens when waves encounter the boundary…
Energy and Power of a Wave
Learning Objectives By the end of this section, you will be able to: All waves carry energy, and sometimes this can be directly observed. Earthquakes can shake whole cities to the ground, performing the work of thousands of wrecking balls…
Wave Speed on a Stretched String
Learning Objectives By the end of this section, you will be able to: The speed of a wave depends on the characteristics of the medium. For example, in the case of a guitar, the strings vibrate to produce the sound.…
Mathematics of Waves
Learning Objectives By the end of this section, you will be able to: In the previous section, we described periodic waves by their characteristics of wavelength, period, amplitude, and wave speed of the wave. Waves can also be described by…
Traveling Waves
Learning Objectives By the end of this section, you will be able to: We saw in Oscillations that oscillatory motion is an important type of behavior that can be used to model a wide range of physical phenomena. Oscillatory motion is also…
