Chapter 10, Problem 37R

To determine

Sound with the same pitch and loudness travelling in the same medium may differ in among the options such as (A) frequency (B) amplitude (C) quality (D) wavelength.

Answer to Problem 37R

The correct option is (C).

Explanation of Solution

Introduction:

Loudness and pitch seem to be same sometimes, but they are not exactly the same. They differ on the basis of their tone quality.

The pitch of a sound is related to the frequency of sound. Whereas, loudness depends on the energy of the wave and the amplitude. In general, the pitch is the reason behind the difference in quality of sounds. The quality difference distinguishes sound with same pitch and loudness.

Conclusion:

Hence, the correct answer is quality.
