Consider the following statements :
Statement-I: Primary waves create density differences in material leading to stretching and squeezing of the material.
Statement-II: Primary waves vibrate perpendicular to the direction of the wave and exerts pressure on material in the direction of propagation.

Which one of the following is correct in respect of the above statements?
(a) Both the statements are true and statement-2 is the correct explanation of statement-1.
(b) Both the statements are true but statement-2 is not the correct explanation of statement-1.
(c) Statement-1 is True and statement-2 is False.
(d) Statement-1 is False and statement-2 is True.

TutorArc · Accepted Answer

Statement 1 is correct: Primary waves (P-waves) vibrate parallel to the direction of the wave. This exerts pressure on the material in the direction of the propagation. As a result, it creates density differences in the material leading to stretching and squeezing of the material.

Statement 2 is not correct: Primary waves (P-waves) vibrate parallel ( and not perpendicular ) to the direction of the wave.
