**Given that,**

Frequency of sound wave = 220 Hz.

Speed of sound wave = 440 m/s.

Calculate wavelength.

We know that, Speed = Wavelength × Frequency

v = λ\( \nu\)

440 = Wavelength × 220

Wavelength = \( \frac{440}{220}\)

Wavelength = 2

Therefore, the wavelength of the sound wave = 2 meters

A sonar device on a submarine sends out a signal and receives an echo 5 s later. Calculate the speed of sound in water if the distance of the object from the submarine is 3625 m.
