Form 4 quiz Waves

In a longitudinal wave, the particles

• remain stationary

• move forward with the speed of the wave

• move backwards and forwards parallel to the direction of travel of the wave

• move from side to side, perpendicular to the direction of travel of the wave

Plane water waves which travel from deep water to shallow water

• are diffracted

• increase their speed

• undergo a change in frequency

• undergo a change in wavelength
