Question
Which of the following statements are true?
i) Direction of wave propagation and particle motion are along the same direction for longitudinal waves
ii) Direction of wave propagation and particle motion are along the same direction for Transverse waves
iii) Direction of wave propagation and particle motion are perpendicular to each other for longitudinal waves
iv) Direction of wave propagation and particle motion are perpendicular to each other for transverse waves
- I and iv are correct
- I and iii are correct
- ii and iv are correct
- ii and iii are correct
Hint:
I and IV are correct
The correct answer is: I and iv are correct
When particles of the medium move in a direction parallel to the direction that the wave moves it is known as longitudinal wave.
When particle motion is perpendicular to the wave motion it is known as transverse waves.
