FREE Waves And Sound Question and Answers
When you pluck a guitar string, it creates waves that are
Transverse waves are created when a guitar string is plucked. To demonstrate, strike a tuning fork and place the vibrating ends in a beaker of water. When the demonstration is over, water is splashing in the beaker and the tuning fork's pitch is dropping.
The sound box on an acoustic guitar amplifies the volume of the sounds the strings produce. This results from the quality known as
Resonance is a phenomena where maximal energy is transferred from the tuning fork to the string and the frequency of the tuning fork (driving frequency) is equal to the frequency of the string (natural frequency). Thus, the string will vibrate with its greatest possible amplitude.
Which of the following could result from completely harmful interference?
A standing wave's node is the location along its length when its amplitude is at its smallest. For instance, the ends of a vibrating guitar string are nodes. An anti-node, or the location where the standing wave's amplitude is at its greatest, is the opposite of a node.
