Advanced Physics: Superposition - Revision Quiz

Test your understanding of Superposition here:

1 / 5

1) The three waves shown in each diagram have the same amplitude and frequency but differ in phase.

They are added together to give a resultant wave.

In which case is the resultant wave zero?

2 / 5

2) Where, in a standing wave, do the vibrations of the medium occur?

At all points between the antinodes.

Only at the antinodes.

At all points between the nodes.

Only at the nodes.

3 / 5

3) The diagram represents a stationary wave on a stretched string.

What is represented by point P and by the length x?

C

A

B

D

4 / 5

4) A stationary wave is produced by two loudspeakers emitting sound of the same frequency.

When a microphone is moved between X and Y, a distance of 1.5 m, six nodes and seven antinodes are detected.

What is the wavelength of the sound?

0.50 m

0.21 m

0.43 m

0.25 m

5 / 5

5) To produce a stationary wave, two waves must travel in opposite directions through the same space.

Which statement about the properties of the two waves must also be true?

The waves must have equal speed, but a different wavelength and frequency.

The waves must have equal speed, frequency and wavelength.

The waves must have equal frequency, but a different speed and wavelength.

The waves must have equal wavelength, but a different speed and frequency.
