Question

what is meaning of saying that 1. the amplitude of sound wave is X, 2.the frequency of sound wave is Y, 3.the wavelength of sound wave is Z​

Answer 1

Answer:

Wavelength:

The minimum distance in which a sound wave repeats itself is called its wavelength. 

Amplitude:

When a wave passes through a medium, the particles of the medium get displaced temporarily from their original undisturbed positions. The maximum displacement of the particles of the medium from their original undisturbed positions, when a wave passes through the medium is called amplitude of the wave. In fact the amplitude is used to describe the size of the wave. 

Frequency:

The number of complete waves or cycles produced in one second is called frequency of the wave. Since one complete wave is produced by one full vibration of the vibrating body, so we can say that the number of vibrations per second is called frequency. 

hope this is helpful.
