The diagram shows a transverse wave.
Which letter represents the amplitude of the wave?
An oceanographic buoy is anchored in a bay to monitor tidal swell. An onboard sensor counts 48 wave crests passing the buoy in exactly 15 seconds. Calculate the frequency of these waves and state the unit.
Primary (P) waves generated during an earthquake are longitudinal waves. Give another example of a longitudinal wave.
Describe the differences between transverse and longitudinal waves in terms of the direction of oscillation and the direction of energy transfer.
