If frequencies are (v-1),(v+1) , then find beats.

If frequencies are (v−1),(v+1)(v-1),(v+1), then find beats.

Options

  1. A2
  2. B1
  3. C3
  4. D4

Correct answer

A. 2

Step-by-step solution

For frequencies v1=v−1andv2=v+1v_1=v-1 and v_2=v+1.  Beats = difference of frequencies =v2−v1=(v+1)−(v−1)=v+1−v+l=2\begin{aligned} \text{ Beats } & =\text{ difference of frequencies } \\ & =v_2-v_1=(v+1)-(v-1)=v+1-v+l=2 \end{aligned}
