What term denotes a region of high pressure or density in a wave?

• A. Compression
• B. Amplitude
• C. Bandwidth
• D. Continuous wave

Answer: (A)

Compression is the region where pressure and density are highest in a wave. In sound and ultrasound waves, particles bunch together in compressions, creating higher pressure and density, while other stretches create rarefactions with lower pressure. The term amplitude describes how large the pressure variation is, not where it occurs; bandwidth relates to the range of frequencies in the signal, and continuous wave refers to the type of waveform, not a physical region of the wave. So the high-pressure, high-density region is the compression.
