Chapter 10.2, Problem 8R

To determine

To explain: The change among the options wave velocity, intensity, pitch, frequency, wavelength, loudness if the radio’s volume is turned up then.

Explanation of Solution

Introduction:

Sound travels in waves, and these waves are characterized by their wavelengths, amplitudes, intensity, and frequency. The volume of sound is proportional to the amplitude and intensity of the sound wave.

The volume is the sensitivity of loudness and determines the intensity of sound. The higher the volume of the sound, the higher is its intensity. As intensity is proportional to the amplitude of the sound wave, hence higher the volume higher is its amplitude. For sound waves, the bigger the amplitude, the louder the sound.

Conclusion:

Hence, as the volume of the radio goes up, the intensity and loudness increase.
