Question

a sound has a higher pitch than a bell. which quantity must also be higher in this sound than in the bell? (1 point)

• frequency
• speed
• amplitude
• wavelength

Explanation:

Pitch of a sound is related to its frequency. Higher pitch means higher frequency. Speed of sound depends on the medium, not pitch. Amplitude relates to loudness, not pitch. Wavelength and frequency are inversely related ($v = f\lambda$), so higher frequency would mean lower wavelength for the same speed. So the quantity that must be higher with higher pitch is frequency.

Answer:

A. frequency
