Question

write the characteristics of a sound waves

Answer 1

there are two characteristic of sound waves.
(1) a wave is produced by the periodic disturbance at a point in a medium.
(2) due to propagation of wave in a medium particles of the medium vibrate about their mean position( without leaving their position) and energy is transfer without a constant speed from one place to medium to the other place

Answer 2

sound travel in form of waves .waves are characterized by three basic qualities.they are speed, frequency, amplitude .Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength.
