9702 U14 Waves Checkpoint Quiz #1

A 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?

A 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?

What is the relationship between the amplitude of a wave and its intensity?

The 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?

The 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?

The 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?
