Question

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

Answer 1

Answer: (D)

1.47 Hz

Answer 2

$\frac{T}{4}=0.17$
or $T=0.68$
Frequency $n=\frac{1}{T}=\frac{1}{0.68}$
$=1.47 \,Hz$
