Explanation:
A longitudinal wave consists of compressions and rarefactions in the medium. Here is a detailed explanation of these terms:
- Longitudinal Wave: A longitudinal wave is a type of wave in which the particles of the medium vibrate parallel to the direction of the wave's propagation. Examples of longitudinal waves include sound waves and seismic waves.
- Compression: In a longitudinal wave, a compression is a region where the particles of the medium are close together. It is a high-pressure region characterized by an increased density of particles.
- Rarefaction: On the other hand, a rarefaction is a region in a longitudinal wave where the particles of the medium are spread apart. It is a low-pressure region characterized by a decreased density of particles.
- Relationship: In a longitudinal wave, compressions and rarefactions alternate as the wave propagates through the medium. The particles in the medium oscillate back and forth, creating areas of compression and rarefaction.
Therefore, the correct answer is B: Compressions and rarefactions in the medium. A longitudinal wave consists of compressions and rarefactions as it propagates through the medium.
