Question

what is the term for the region of high pressure created in the air when a vibrating object moves forward? choose 1 answer: a refraction b dispersion c compression d rarefaction

Explanation:

When a vibrating object moves forward in air, it pushes the air particles close together creating a region of high - pressure. This region of high - pressure in a sound wave is called compression. Refraction is the bending of a wave when it enters a new medium. Dispersion is the separation of a wave into its component frequencies. Rarefaction is the region of low - pressure in a sound wave.

Answer:

C. Compression
