Question

In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.17 s. The frequency of the wave is (A) 1.47 Hz (B) 0.36 Hz (C) 0.73 Hz (D) 2.94 Hz

Time for maximum displacement t=0.17 s Time period T for one vibration =4 t=4 × 0.17=0.68 s Frequency =(1/ text time period (T))=(1/0.68) =1.47 Hz

Q. In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is $0.17 s$ . The frequency of the wave is

1.47 Hz

0.36 Hz

0.73 Hz

2.94 Hz

Time for maximum displacement $t = 0.17 s$ Time period $T$ for one vibration
$= 4 t = 4 \times 0.17 = 0.68 s$
Frequency $= \frac{1}{time period ( T )} = \frac{1}{0.68}$
$= 1.47 Hz$
