A longitudinal wave is moving through a medium. Which of the following statements about the direction of propagation of wave and displacement of the medium is true?
Correct answer: A. Displacement of medium = parallel to the energy transfer direction of propagation of wave = parallel to the energy transfer.
- A. Displacement of medium = parallel to the energy transfer direction of propagation of wave = parallel to the energy transfer.
- B. Displacement of medium = parallel to the energy transfer direction of propagation of wave = perpendicular to the energy transfer
- C. Displacement of medium = perpendicular to the energy transfer direction of propagation of wave = parallel to the energy transfer.
- D. Displacement of medium = perpendicular to the energy transfer direction of propagation of wave = perpendicular to the energy transfer.
Explanation
Option A is correct since it mentions the characteristics of a longitudinal wave.Option B is incorrect since it mentions the characteristics of a transverse wave.Option C is incorrect since it mentions the characteristics of a transverse wave in an opposite way.Option D is incorrect since it mentions the characteristics of a transverse wave but the first statement is wrong.
