In a sinusoidal wave, the minimum time required for a particular point to move from maximum displacement to zero displacement is $0.17\text{ s}$. The frequency of the wave is
$1.47\text{ Hz}$
$0.36\text{ Hz}$
$0.73\text{ Hz}$
$2.49\text{ Hz}$
Solution
Here, $\frac{T}{4} = 0.17\text{ s}$
$\therefore f = \frac{1}{T} = \frac{1}{4 \times 0.17}\text{ Hz}$
The frequency of the wave, $f = 1.47\text{ Hz}$
