Aguitar string is plucked. what best describes the formation and transmission of the sound wave?

the string vibrates the surrounding air, which produces a transverse wave.
the string vibrates the surrounding air, which produces a longitudinal wave.
the string produces a longitudinal wave that travels without a medium.
the string produces a transverse wave that travels without a medium.

The correct answer to the question is : B) The string vibrates the surrounding air, which produces a longitudinal wave.

EXPLANATION :

Before coming into any conclusion, first we have to understand sound wave.

A sound wave is a longitudinal wave in which the vibration of particles is parallel to the direction of wave propagation. It moves in a series of compression and rarefaction.

As it is a longitudinal wave, it needs a medium for its propagation. It can not propagate without any medium. The medium may be solid,liquid or air.

Hence, the correct answer of this question is that the string vibrates the surrounding air, which produces a longitudinal wave.

the bal will not change its velocity.

i think the answer would be reserve.
