The sound created in a big hall persists because of the repeated reflections. The phenomenon is called

Options

  1. AReverberation.
  2. BDispersion.
  3. CRefraction.
  4. DDiffraction.

Correct answer

A. Reverberation.

Step-by-step solution

- Reverberation is the persistence of sound after the sound source has been stopped. It results from a large number of reflected waves which can be perceived by the brain as a continuous sound. On the other hand, an echo occurs when a pulse of sound can be heard twice.
