In a series of standing waves, what is the relationship between the fundamental frequency and the frequencies of the harmonics?

• The harmonics have frequencies that are multiples of the fundamental frequency.

• The harmonics have frequencies that are fractions of the fundamental frequency.

• The harmonics have frequencies that are unrelated to the fundamental frequency.

• The harmonics have frequencies that are the square root of the fundamental frequency.

What is a node in a standing wave?

• A point where the wave is as far as it gets from equilibrium

• A point where the string stays at its equilibrium position

• A point where the wave changes direction
