Question

1. In a

wave, the particles of the
medium move in the same direction as the
wave motion.

Answer 1

Yes, true

Step-by-step explanation:

In a wave, especially in longitudinal waves, the particles move in the same direction as the wave is moving which means they are parallel.

Answer 2

In sound waves, the particles move in the same direction as the wave is moving, so you wouldn't be able to see them like ripples in the air, instead they make areas in the air where the particles are more squished together, and areas where the particles are further apart.
