A sound wave can be described completely by its five characteristics:
Amplitude of the wave is the magnitude of the maximum disturbance in the medium on either side of the mean value
The difference between a male’s voice and female’s is because the voice of a male has a lower frequency which contributes to the deepness or the bass in the voice. Female, in contrast, has a voice with higher frequency resulting in a higher shrillness or pitch.
The speed of sound is defined as the distance which a point on a wave, such as a compression or a rarefaction, travels per unit time.
We know that,
λ is the wavelength of the sound wave, which is the distance travelled by the sound wave. Then we get:
That is, Speed / Velocity of wave = Frequency x Wavelength
