Answer 1

The medium vibrates in all directions.north.south.

Answer 2

Explanation :

We know that there can be different types of waves. It can be longitudinal and transverse wave as well.

In longitudinal wave, the particles of wave move parallel in the direction of propagation of wave while the medium vibrates in the direction of the wave.

The longitudinal waves travel in the form of compressions and rarefactions.

Hence, the correct option is (C).
