MCQ
Beats are the result of
  • A
    Diffraction
  • B
    Destructive interference
  • C
    Constructive and destructive interference
  • Superposition of two waves of nearly equal frequency

Answer

Correct option: D.
Superposition of two waves of nearly equal frequency
d
(d) Beats is the superposition of two waves of nearly equal frequencies. When the two tones are close in pitch but not identical, the difference in frequency generates the beating The volume varies like in a tremolo as the sounds alternately interfere constructively and destructively.
