Question

a region where the particles are pushed closer together. a region where the particles are spread apart the most. the distance between corresponding points of two consecutive waves. wavelength rarefaction compression amplitude crest

Explanation:

1. The definition "A region where the particles are pushed closer together" matches the term Compression, which is the dense region in a longitudinal wave.
2. The definition "A region where the particles are spread apart the most" matches the term Rarefaction, which is the sparse region in a longitudinal wave.
3. The definition "The distance between corresponding points of two consecutive waves" matches the term Wavelength.

Answer:

• "A region where the particles are pushed closer together" → Compression
• "A region where the particles are spread apart the most" → Rarefaction
• "The distance between corresponding points of two consecutive waves" → Wavelength
