D. At an unpredictable angel
Answer:
parallel to
Explanation:
In parallel direction the air particles vibrate with respect to the direction the sound wave travels. The correct option is B.
What is sound wave?A sound wave is the pattern of disturbance caused by the movement of energy as it propagates away from the source of the sound through a medium (such as air, water, or any other liquid or solid matter).
Sound waves are produced by object vibrations and pressure waves, such as a ringing cellphone.
Because sound waves are produced by compressions and rarefactions in the air, they are referred to as longitudinal waves. The air particles vibrate in a direction parallel to the propagation direction.
The particles in a longitudinal wave are displaced parallel to the direction of the wave. Compressions moving along a slinky are an example of longitudinal waves.
Air particles vibrate in a parallel direction to the direction of travel of the sound wave.
Thus, the correct option is B.
