Beats are produced by frequencies $v_1$ and $v_2\left(v_1>v_2\right)$. The duration of time between two successive minima is
  1. $\frac{1}{v_1+v_2}$
  2. $\frac{2}{v_1-v_2}$
  3. $\frac{2}{v_1+v_2}$
  4. $\frac{1}{v_1-v_2}$

Solution

The time interval between two successive beats $\mathrm{T}=\frac{1}{\text { Beat frequency }}=\frac{1}{\mathrm{f}_1-\mathrm{f}_2}$
