Question

what are the characteristics of sound?? define them​

Answer 1

Answer:

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.

Answer 2

Answer:

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.

1. Wavelength - The minimum distance in which a sound wave repeats itself is called its wavelength.
2. Amplitude - When a wave passes through a medium, the particles of the medium get displaced temporarily from their original undisturbed positions.
3. Time-Period - The time required to produce one complete wave or cycle or cycle is called time-period.
4. Frequency - The number of complete waves or cycles produced in one second is called frequency.
5. Velocity or Speed - The distance travelled by a wave in one second is called velocity or speed.
