select the correct answer. which statement is true for particles of the medium of an earthquake p - wave? a. they vibrate in a direction parallel to that of the wave, forming crests and troughs. b. they vibrate in a direction parallel to that of the wave, forming compressions and rarefactions. c. they vibrate in a direction perpendicular to that of the wave, forming crests and troughs. d. they vibrate in a direction perpendicular to that of the wave, forming compressions and rarefactions.
Answer
Brief Explanations:
P - waves are longitudinal waves. In longitudinal waves, particles of the medium vibrate parallel to the direction of wave - propagation and form compressions and rarefactions.
