Sound waves are longitudinal waves that travel through a medium by compressing and rarefying particles, allowing us to perceive sound. They are characterized by properties such as frequency, wavelength, amplitude, and speed, which determine the pitch, loudness, and timbre of the sound we hear.

Sound Waves

Sound waves

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation, commonly exemplified by sound waves in air. These waves consist of compressions and rarefactions, where particles are alternately pushed together and pulled apart as the wave travels through a medium.

Amplitude of sound

The speed of sound is the rate at which sound waves travel through a medium, influenced by the medium's properties such as temperature, density, and elasticity. In dry air at 20°C (68°F), it is approximately 343 meters per second (1,125 feet per second), but it varies in different materials and conditions.
