Breakdown the Problem

1. Identify the key terms in the question related to longitudinal waves.
2. Determine the segments of longitudinal waves that correspond to the described condition (coils spread apart).

Relevant Concepts

1. Longitudinal waves consist of compressions and rarefactions.
2. Compressions are areas where the particles of the medium are bunched together, while rarefactions are areas where they are spread apart.

Analysis and Detail

1. In a longitudinal wave, the motion of the medium is parallel to the direction of the wave.
2. This means that as the wave travels, there are regions where the coils (or particles) are compressed together (compressions) and regions where they are spread out (rarefactions).

Verify and Summarize

• Given that the question specifies the parts of longitudinal waves where the coils are spread apart, it directly correlates to the definition of rarefactions.

Final Answer

The parts where the coils are spread apart in longitudinal waves are called rarefactions.
