a. Decreased. b. increased. c. Neither lessened nor increased.
22. A wave travels an median distance of 1 meter in 1 2nd with a frequency that 1 Hz. That is amplitude is
a. Less than 1 meter. b. 1 meter. c. Much more than 1 meter. d. not enough information come say.
23. Sound travels v the wait in the type of
a. Transverse waves, b. longitudinal waves,
24. and radio signals travel through the waiting in the type of
a. Transverse waves. b. Longitudinal waves.
25. Pitch coincides to
a. frequency, b. Noise, c. Loudness,
26. whereas amplitude corresponds to
a. Frequency. b. Noise. c. Loudness.
27. A vibrating tuning fork causes an the same fork surrounding to vibrate. This is referred to as
a. Refraction. b. Resonance. c. Beats. d. Reverberation.
Reasoning: See web page 389 the the textbook for much more information.
28. For this come happen, both forks must have the same (or multiple)
