What causes the formation of beats in sounds?

Options

  1. ADispersion
  2. BReflection
  3. CRefraction
  4. DInterference

Correct answer

D. Interference

Step-by-step solution

We know that, interference of two sounds having equal amplitude and constant phase difference but slightly different frequency causes formation of beats.
