1A wave pulse moves along a stretched rope in the direction shown.
Which diagram shows the variation with time t of the displacement s of the particle P in the rope?
- AA
- BB
- CC
- DD
- AA
2A wave has period T, wavelength λ and amplitude A. The wave is shown on a graph of displacement x against distance d.
Which graph is correctly labelled?- AA
- BB
- CC
- DD
- AA
3What is the relationship between the amplitude of a wave and its intensity?
- AA
- BB
- CC
- DD
- AA
4The diagram shows two waves R and S.
Wave R has an amplitude of 8 cm and a period of 30 ms.
What are the amplitude and the period of wave S?
- AA amplitude = 2 cm; period = 10 ms.
- BB amplitude = 2 cm; period = 90 ms.
- CC amplitude = 4 cm; period = 10 ms.
- DD amplitude = 4 cm; period = 90 ms.
5The graph shows the variation with time of the displacement X of a gas molecule as a continuous sound wave passes through a gas.
The velocity of sound in the gas is 330 m.s^–1. All the graphs below have the same zero time as the graph above.
What is the displacement-time graph for a molecule that is a distance of 0.165 m further away from the source of the sound?
- AA
- BB
- CC
- DD
- AA
6The diagram shows a long rope fixed at one end. The other end is moved up and down, setting up a stationary wave.
What is the phase difference between the oscillations at X and at Y?
- AA 0
- BB 45°
- CC 90°
- DD 135°
