Question

In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is 0.14 s. The frequency of the wave is (A) 0.42 Hz (B) 2.75 Hz (C) 1.79 Hz (D) 0.56 Hz

Time Taken by the wave to travel a distance equal to one wavelength =0.14× 4 =0.56s Frequency fc=(I/T) =(1/0.56) f=(100/56) Or f=1.79 Hz

Q. In a sinusoidal wave, the time required for a particular point to move from maximum displacement to zero displacement is $0.14 s$ . The frequency of the wave is

0.42 Hz

2.75 Hz

1.79 Hz

0.56 Hz

3.5 Hz

Time Taken by the wave to travel a distance equal to one wavelength
$= 0.14 \times 4$
$= 0.56 s$
Frequency $f_{c} = \frac{I}{T}$
$= \frac{1}{0.56}$
$f = \frac{100}{56}$
Or $f = 1.79 Hz$
