Straight wavefronts on the surface of a ripple tank approach a gap in a barrier.

The diagram shows how the wavefronts change shape as they pass through the gap.

What is the name of this effect?

• diffraction

• propagation

• reflection

• refraction

Which statement about waves is correct?

• All waves can travel through a vacuum.

• All waves travel at the same speed.

• Seismic S-waves can be modelled as longitudinal waves.

• Waves transfer energy without transferring matter.

The diagram shows a transverse wave.

Which row identifies the amplitude and the wavelength of the wave?

• amplitude: P, wavelength: R

• amplitude: P, wavelength: S

• amplitude: Q, wavelength: R

• amplitude: Q, wavelength: S

A student writes down some facts about two transverse waves. Wave 1 has a frequency f and a velocity v. Wave 2 has four times the frequency of wave 1 and is travelling at a velocity of 2v. What is the wavelength of wave 2 in terms of f and v?

• 8fv

The figure is a scale diagram of wavefronts of red light approaching a gap in a barrier. What will the wavefronts look like after the wave has passed through the gap?
