Answer : A sound wave traveling eastward through air causes the air molecules to vibrate east and west

Explanation :

We know that the sound wave is a longitudinal wave. The particles of medium travels in the direction of propagation of the wave. The space where the particles are closely spaced is called compression and the space where the particles are far apart is called rarefaction. Also, the distance between two consecutive compression and rarefaction is called the wavelength.

If the sound wave is travelling in eastward direction, then the air molecules will move in the direction of propagation of wave. They will vibrate either in east or west direction.

So, the correct option is (1) " vibrate east and west ".
