Question 21

21

Which statement about longitudinal waves and transverse waves is not correct? Both waves can be polarised. Both waves can form stationary waves. Both waves can transfer energy as progressive waves. Both waves obey the equation \(v=f \lambda\).

Answer

A

Question 22

22

Which statement about longitudinal waves is correct? Longitudinal waves include radio waves travelling through air. Particles in a longitudinal wave vibrate at right-angles to the direction of transfer of wave energy. Some types of longitudinal wave can be polarised. Stationary waves can be produced by the superposition of longitudinal waves.

Question 4(a)

4(a)

A progressive longitudinal wave travels through a medium from left to right. Fig. 4.1 shows the positions of some of the particles of the medium at time \(t_{0}\) and a graph showing the particle displacements at the same time \(t_{0}\). Particle displacements to the right of their equilibrium positions are shown as positive on the graph and particle displacements to the left are shown as negative on the graph. The period of the wave is T.
