A) 1.47 Hz
B) 2.94 Hz
C) 4.17 Hz
D) 0.92 Hz
Correct Answer: A
Solution :
Key Idea: Frequency is reciprocal of time period. For a sinusoidal wave, time period is \[T=4t\] Time required for maximum displacement is \[T=4\times 0.17\] Also frequency is inverse of time period, hence, \[n=\frac{1}{T}=\frac{1}{0.68}=1.47\,Hz.\]You need to login to perform this action.
