In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.170. The frequency of the wave will be:
A) 2.94 Hz
B) 0.73 Hz
C) 0.36 Hz
D) 1.47 Hz
Correct Answer:
D
Solution :
\[\frac{T}{4}=0.17\] or \[T=0.68\] Frequency \[n=\frac{1}{T}=\frac{1}{0.68}=1.47\,Hz\]
