Question
Two tuning forks of frequency 250 Hz and 256 Hz produce beats. If a maximum of intensity is ob-served just now, after how much time the minimum is observed at the same place?
Options
A.$\frac{1}{18}$sec.
B.$\frac{1}{4}$ sec.
C.$\frac{1}{3}$ sec.
D.$\frac{1}{12}$sec.
Solution
Sol. Beat frequency = 256 – 250 = 6 H2
⇒ T = $\frac{1}{6}$ s
⇒ Time of maxima to minima = $\frac{T}{2} = \frac{1}{12}$sec
