Question

What are the properties of sound waves?

Answer 1

Hint: Sound waves get generated because of the vibrations of the objects. Basically, the sound waves are referred to as disturbance. The amplitude of the sound waves determines loudness and the frequency of the sound waves determine the pitch. Sound waves fall into 3 categories of different ranges of frequencies, such as audible, infrasonic and ultrasonic waves. ]

Complete step-by-step solution:
The sound waves are the longitudinal waves with frequencies ranging from that of the audible, infrared and ultrasonic waves.
Amplitude is the maximum distance the particles in a medium move from their rest positions. Sound is produced by vibrations. The energy in a sound wave increases, its amplitude increases. Loudness is how we perceive the energy of a sound wave.
Sound waves will move at a constant speed unless: they are moving through different mediums, they are moving in mediums of different temperatures, the source creating the sound.
Loudness distinguishes between loud and feeble sound. Loudness mainly depends upon the amplitude of the sound. Pitch distinguishes between shriller and falter sound. Pitch mainly depends upon the frequency of sound. Quality or timbre distinguishes one sound from another having the same loudness and pitch. Quality or timbre – both the sounds have different sound effects.
\[\therefore \]The properties of the sound waves are loudness, pitch and quality or timbre.

Note: The sound waves can be reflected, refracted, diffracted and produces interference effects. The sound waves can be louder or softer, they can be of a high or low pitch and they can be melodic or just noisy. A sound wave is a mechanical wave that belongs to a sub-type of the longitudinal wave.
