The sound source of a ship’s sonar system operates at a frequency of 22.0 kHz . The speed of sound in water (assumed to be at a

Dafna1 [17]

Answer:

$\Delta f=f_{Lr}-f_{Se}$

147.45 Hz

Explanation:

v = Speed of sound in water = 1482 m/s

$v_w$ = Speed of whale = 4.95 m/s

Frequency of the wave in stationary condition

$f_{Lr}=f\dfrac{v+v_w}{v-v_w}$

Ship's frequency which is reflected back

$f_{Se}=f\dfrac{v}{v-v_w}$

The difference in frequency is given by

$\Delta f=f\dfrac{v+v_w}{v-v_w}-f\dfrac{v}{v-v_w}\\\Rightarrow \Delta f=f_{Lr}-f_{Se}$

$\mathbf{\Delta f=f_{Lr}-f_{Se}}$

$f_{Lr}=22\times \dfrac{1482+4.95}{1482-4.95}\\\Rightarrow f_{Lr}=22.14745\ kHz$

$f_{Se}=22\ kHz$

$\Delta f=f_{Lr}-f_{Se}\\\Rightarrow \Delta f=22.14745-22\\\Rightarrow \Delta f=0.14745\ kHz\\\Rightarrow \Delta f=147.45\ Hz$

The difference in wavelength is 147.45 Hz
