a. Decreased. b. increased. c. Neither lessened nor increased.
22. A wave travels an median distance that 1 meter in 1 second with a frequency the 1 Hz. The amplitude is
a. Less than 1 meter. b. 1 meter. c. An ext than 1 meter. d. not enough information come say.
23. Sound travels with the air in the kind of
a. Transverse waves, b. longitudinal waves,
24. and radio signals travel through the wait in the form of
a. Transverse waves. b. Longitudinal waves.
25. Pitch synchronizes to
a. frequency, b. Noise, c. Loudness,
26. whereas amplitude synchronizes to
a. Frequency. b. Noise. c. Loudness.
27. A vibrating tuning fork causes an the same fork nearby to vibrate. This is called
a. Refraction. b. Resonance. c. Beats. d. Reverberation.
Reasoning: See page 389 of the textbook for much more information.
