Which of the following statements about standing waves is not true?

• Particles between adjacent nodes oscillate with varying amplitudes.

• Particles between adjacent nodes are moving in phase with each other.

• Particles immediately either side of a node are moving in opposite directions

• Particles undergo no disturbance at an antinode.

A glass tube, closed at one end, has a loudspeaker placed at the other end. This is used to create a vibrating column of air, producing sound.

The wave in the tube is best described as

• longitudinal and progressive

• longitudinal and standing.

• transverse and progressive.

• transverse and standing.

In an Open-Ended Air Column, when the length of the tube increases, what happens to the Fundamental Frequency?

• The Fundamental Frequency increases.

• The Fundamental Frequency decreases.

• The Fundamental Frequency stays the same.

In an Closed-Ended Air Column, when the length of the tube increases, what happens to the Fundamental Frequency?

• The Fundamental Frequency increases.

• The Fundamental Frequency decreases.

• The Fundamental Frequency stays the same.

In an Open-Ended Air Column, when the length of the tube increases, what happens to the Wavelength?

• The Wavelength increases.

• The Wavelength decreases.

• The Wavelength stays the same.

In an Closed-Ended Air Column, when the length of the tube increases, what happens to the Wavelength?

• The Wavelength increases.

• The Wavelength decreases.

• The Wavelength stays the same.

In an Open-Ended Air Column, when the length of the tube increases, what happens to the Wave Speed?

• The Wave Speed increases.

• The Wave Speed decreases.

• The Wave Speed stays the same.

In an Closed-Ended Air Column, when the length of the tube increases, what happens to the Wave Speed?

• The Wave Speed increases.

• The Wave Speed decreases.

• The Wave Speed stays the same.

When you increased the fundamental frequency, what happened to the pitch?

• The pitch had no change.

• The pitch was lower.

• The pitch was higher.
