The pitch.
Pitch
The frequency of a sound is what determines the pitch. A greater frequency (a faster vibration of the air) corresponds to a higher pitch, while a small frequency is what we hear as a low sound.
With your ears. The faster the vibration, the higher the frequency. A low frequency vibration will be felt more than heard.
Vibration and rate of vibration.
Frequency
Frequency
The rate of vibration is called the frequency.
By vibration of vocal chords.. High frequency of vibration/low pitch = sweet sound Low frequency of vibration/high pitch = harsh sound High amplitude = loud sound
Increase the frequency of vibration.
No. If a vibration is smaller, the sound is higher pitched. To get a quieter sound the amplitude of the sound-wave needs to be smaller. +++ It depends whether you mean amplitude or wavelength being "smaller", and they are two different things. If the vibration's amplitude is smaller the sound is quieter irrespective of frequency. If the vibration is more rapid, the frequency is higher but the wavelength correspondingly smaller irrespective of amplitude.
It becomes a lower frequency.
The vibration of air or a material.
