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