What are the characteristics of a sound wave?

1.	What are the characteristics of a sound wave?
Answer» The characteristics of a sound wave, which play an important role in describing the nature of a wave are 1. Wavelength (λ) 2. Amplitude (A) 3. Frequency (υ) 4. Wave speed (v) There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself. Wavelength : Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave. velocity :The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north). Time period :The time taken by a particle of medium to complete its one vibration is called the time period of the wave. ortime period is the time taken by a vibrating body to complete one oscillation time period is represented by the letter T. second (s) is the SI unit of time period. Amplitude : The amplitude of a periodic variable is a measure of its change in a single period. The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values. frequency :Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency .

There are five main characteristics of sound waves: wavelength, amplitude, frequency, time period, and velocity. The wavelength of a sound wave indicates the distance that wave travels before it repeats itself.

Wavelength : Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.

velocity :The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).

Time period :The time taken by a particle of medium to complete its one vibration is called the time period of the wave.

ortime period is the time taken by a vibrating body to complete one oscillation
time period is represented by the letter T.
second (s) is the SI unit of time period.

Amplitude : The amplitude of a periodic variable is a measure of its change in a single period. The amplitude of a non-periodic signal is its magnitude compared with a reference value. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values.

frequency :Frequency is the number of occurrences of a repeating event per unit of time. It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency
