Physics - Sound Wave Question with Solution | TestHub

Given frequencies of the tuning forks are $n_1=256$ Hz and $n_2=258$ Hz.

The beat frequency is given by the difference between the two frequencies:

$n=|n_1-n_2|=|256-258|=2$ Hz

The time interval between two consecutive maxima is the beat period, which is the reciprocal of the beat frequency:

$T=\frac{1}{n}=\frac{1}{2}=0.5$ s

Answer: 0.5 s
