20 Hertz
An electric quitar is generating a sound of constant frequency. An increase in which sound wave charateristic would result in an increase in loudness?
Period
In a demonstration, a vibrating tuning fork causes a nearby second tuning fork to begin to vibrate with the same frequency. Which wave phenomenon is illustrated by this demonstration?
Resonance
Two waves traveling in the same medium interfere to produce a standing wave. What is the phase difference bwteen the two waves at a node?
180 degrees
