A) 1.47 Hz
B) 0.36 Hz
C) 0.73 Hz
D) 2.94 Hz
Correct Answer: A
Solution :
If T is the time period, then time required for a point to move from maximum displacement is zero displacement is \[\frac{T}{4}\]. \[\therefore \frac{T}{4}=0.170\] or \[T=0.170\times 4=0.680\,s\] Therefore, the frequency of wave is \[n=\frac{1}{T}=\frac{1}{0.680}=1.47\,Hz\]You need to login to perform this action.
