Q. Two tuning forks have frequencies 380 and $384\, Hz$ respectively. When they are sounded together, they produce 4 beats. After hearing the maximum sound, how long will it take to hear the minimum sound

Waves

Solution:

Beat period $T=\frac{1}{n_{1} \sim n_{2}}$
$=\frac{1}{384-380}=\frac{1}{4} \sec.$
Hence minimum time interval between maxima and minima
$t=\frac{T}{2}=\frac{1}{8} \sec$
