Medical ultrasound often uses a frequency of 3.5 MHz. What is the wavelength of these ultrasound waves? Assume that the speed of sound waves in the human body is 1,500 m/s, the same as the speed of sound in salt water.

We know that the speed of sound in human body is , and we know the used ultrasOund frequency to equal f=3.5MHz
Now using formula (1) we calculate the wavelength of the ultrasound waves in the human body:
Rearranging for lambda we get:
Now plugging in the values we get:
Result:
The wavelength of ultrasound waves in the human body is
