• A. Rarefaction
• B. Condensation
• C. Frequency$f$
• D. Amplitude$A$

Answer: (B)

Verified step by step guidance

1. Understand that a sound wave traveling through a medium consists of alternating regions of compression and rarefaction.
2. Recognize that the term 'density' in this context refers to the concentration of particles in the medium at a specific region of the wave.
3. Identify that the compression region is where particles are pushed closer together, resulting in a higher density than the average.
4. Know that the term used to describe this increased particle density in the compression region is 'condensation'.
5. Differentiate 'condensation' from 'rarefaction' (which is the region of lower particle density), and from other terms like frequency (number of wave cycles per second) and amplitude (maximum displacement of particles).
