Study Notes
Sound Waves
- Sound waves are the most important example of longitudinal waves.
- A vibrating body produces sound waves.
- Compressions are regions where particles are close together (high pressure).
- Rarefactions are regions where particles are spread apart (low pressure).
Characteristics of Sound Waves
- Sound waves are a form of energy propagated through a medium in the form of waves.
- The frequency of vibration of the source determines whether sound waves can be heard.
- Sound waves can only travel through a medium, such as a solid, liquid, or gas, not a vacuum.
Importance of Sound
- Sound helps animals detect dangers and hazards before they affect them.
Chapter Outcome
- Recognize and appreciate the importance of the nature of wave's characteristics and components in daily activities.
- Analyze characteristics, concept, and components of waves.
- Elaborate on the properties and categories of waves.
- Design methods of production and transmission of sound waves and their applications.
- Compute the speed of sound relative to its temperature.
- Analyze the Doppler Effect.
- Distinguish between loudness and intensity of sound, intensity and intensity level, music and noise, and stringed and non-stringed music instruments.
Introduction to Waves
- Waves transfer energy.
- Waves are important in understanding sound and other forms of wave motion.
- Periodic vibrations can cause disturbances that move through a medium in the form of waves.
- Many kinds of waves occur in nature, such as sound waves, water waves, and electromagnetic waves.
Longitudinal Waves
- Longitudinal waves are produced when particles of the medium oscillate parallel to the direction of propagation.
- No crests and troughs are formed in longitudinal waves.
- Compressions and rarefactions are formed in the medium as particles move closer together or farther apart.
- The wavelength (l) of a wave is the distance from a compression to a compression, or from rarefaction to rarefaction.
Types of Waves
- Traveling waves are disturbances that travel through a medium.
- Standing waves are waves that do not appear to be propagating, also called stationary waves.
