|
|
Amplitude is the tone or timbre of a sound, whereas frequency is the pitch.
|
|
|
Amplitude is detected int he cochlea, whereas frequency is detected in the auditory cortex.
|
|
|
Amplitude is the height of the sound wave, whereas frequency is a measure of how frequently the sound waves pass a given point.
|
|
|
Frequency is a measure for light waves, whereas amplitude is a measure for sound waves.

Detailed explanation-1: -[BL] For sound, a higher frequency corresponds to a higher pitch while a lower frequency corresponds to a lower pitch. Amplitude corresponds to the loudness of the sound. [BL][OL] Since sound at all frequencies has the same speed in air, a change in frequency means a change in wavelength.
Detailed explanation-2: -What is the principle difference between amplitude and frequency in the context of sound waves? Amplitude is height of sound wave and frequency is the measure of how frequently the the sound waves pass a given point.
Detailed explanation-3: -The relationship between the wave’s amplitude and frequency is such that it is inversely proportional to the frequency. The amplitude decreases as the frequency increases. The amplitude increases as the frequency decreases.
Detailed explanation-4: -What is Amplitude of Sound? The amplitude of a sound wave is the measure of the height of the wave. The amplitude of a sound wave can be defined as the loudness or the amount of maximum displacement of vibrating particles of the medium from their mean position when the sound is produced.
Detailed explanation-5: -Amplitude is the maximum displacement from its mean position to extreme position of a particle of the medium in which a wave propagates.
