definition of amplitude wavelengths amplitude and pitch
The pitch or note of a sound that we experience is determined by its wavelength or its frequency. The shorter the wavelength, the higher the frequency becomes, and the higher the pitch that we hear.The amplitude of a sound wave is the same thing as loudness.The loudness or amplitude corresponds to how much the wave is compressed.he pitch or note of a sound that we experience is determined by its wavelength or its frequency. The shorter the wavelength, the higher the frequency becomes, and the higher the pitch that we hear.
