How do loudness and pitch of sound depend on amplitude and frequency respectively?
If the sound waves have a small amplitude,then the sound will be faint.On the other hand if the sound waves have a large amplitude,then the sound will be loud.
The pitch of a sound is directly proportional to its frequency. Sounds of low frequency are said to have low pitch whereas sounds of high frequency are said to have high pitch.
The amplitude of a sound wave is the same thing as its loudness. Since sound is a compression wave, its loudness or amplitude would correspond to how much the wave is compressed.
A sound wave will spread out after it leaves its source, decreasing its amplitude or loudness.
Pitch depends on the frequency.
IE: Short wavelengts have higher frequency.
The relationship between velocity, wavelength and frequency is:v=wf or velocity=wavelengt X frequency
If there is some absorption in the material, the loudness of the sound will decrease as it moves through the substance.
If it hits a hard surface it will bounce, (echoe).
