Sonar is a device that uses reflected sound waves to measure underwater depths. If a sonar signal has a frequency of 288 Hz, and the wavelength is 5.00 m, what is the speed of the sonar signal in water?

Sagot :

Given that,

The frequency of a sonar signal, f = 288 Hz

Wavelength = 5 m

To find,

The speed of the sonar signal in water.

Solution,

Let the speed of the sonar signal is v. The speed in terms of wavelength and frequency is given by :

[tex]v=f\lambda\\\\v=288\times 5\\\\v=1440\ m/s[/tex]

So, the speed of the sonar signal in water is 1440 m/s.
