Detailed explanation-1: -In vision, the amplitude of a light wave relates to our perception of the brightness of a stimulus.
Detailed explanation-2: -In the visual system, a light wave’s wavelength is generally associated with color, and its amplitude is associated with brightness. In the auditory system, a sound’s frequency is associated with pitch, and its amplitude is associated with loudness.
Detailed explanation-3: -Brightness refers to the intensity of the color and depends on the amplitude or the distance between the midpoint and the peak of the wave.
Detailed explanation-4: -The loudness of a given sound is closely associated with the amplitude of the sound wave. Higher amplitudes are associated with louder sounds. Loudness is measured in terms of decibels (dB), a logarithmic unit of sound intensity.
