Question

A string with both ends held fixed is vibrating in its third harmonic. The waves have a speed of 188 m/s and a frequency of 220 Hz. What is the amplitude of the standing wave at an antinode?

Answer 1

The amplitude of the standing wave at an antinode cannot be determined without additional information.

Step-by-step explanation:

The amplitude of the standing wave at an antinode can be determined by considering the characteristics of the wave and the properties of the string. In a standing wave, the amplitude at an antinode is equal to twice the amplitude of the individual waves that superpose to create the standing wave. Therefore, the amplitude of the standing wave at an antinode is double the amplitude of the individual waves. However, the given question does not provide information about the amplitude of the individual waves, so we cannot determine the amplitude of the standing wave at an antinode.
