Question

Quizplus · Accepted Answer

Loudness and pitch are both related to the perception of sound, while brightness and hue are both related to the perception of color. Loudness is a measure of the intensity or amplitude of a sound, while pitch is a measure of the frequency of the sound wave. Similarly, brightness is a measure of the intensity or luminance of a color, while hue is a measure of the dominant wavelength of the light. Therefore, the relationship between loudness and pitch is analogous to the relationship between brightness and hue.
