Study Notes
Sound Waves
- Sound waves are mechanical waves.
- Sound is defined as a vibration that travels through a medium, such as air, water, or solid objects, and can be heard when it reaches a person's ear.
Characteristics of Sound Waves
- In air, sound waves are characterized as longitudinal waves, meaning that the particles of the medium (air molecules) vibrate back and forth along the direction of the wave.
Description of Waves
- A wave is described in terms of its wavelength, frequency, amplitude, and speed.
Production of Sound Waves
- Sound waves are produced when an object vibrates, creating a disturbance in the air particles around it, which then transmit the energy through the air as a pressure wave.
Energy and Medium
- Sound waves produce kinetic energy.
- The medium through which sound waves travel is the air (or any other medium it passes through, such as water or solid objects).
