Question

1. which of the following properties of sound would be the most similar to the color or hue of light?

a. pitch
b. loudness
c. purity
d. amplitude

Explanation:

• Pitch: Pitch of sound is related to frequency. Hue (color) of light is related to its frequency (or wavelength). Just as different frequencies of light give different colors (hues), different frequencies of sound give different pitches.
• Loudness: Loudness of sound is related to amplitude. In light, it is more related to brightness (intensity) rather than color (hue).
• Purity: Purity of sound is related to the presence of harmonics. In light, it is not directly comparable to hue.
• Amplitude: As mentioned above, amplitude of sound is related to loudness. In light, amplitude (in a wave - like description) is related to intensity (brightness) not hue.

Answer:

a. Pitch
