1) 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, frequency and wavelength.

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

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

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

2) A stationary wave is set up on a stretched string, as shown.

Which statement about the points on the string is correct?

The horizontal distance between R and S is half the wavelength.

Points P and R vibrate in phase.

Point S is an antinode.

Point Q vibrates with the largest amplitude.

4) 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?

5 / 5

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

Only at the nodes.

At all points between the nodes.

Only at the antinodes.
