Question

What is frequency of a 0.0004 m ultrasonic wave passing through human tissue? Assume speed of sound in human tissue is 1500 m/s. Formula f= v/¥

Answer 1

Given:

the speed of sound in human tissue is

`v=1500\text{ m/s}`

the wavelength of the wave is

`\lambda=0.0004\text{ m}`

Required: frequency of the wave.

Step-by-step explanation:

to find the frequency of the wave we use the relation that is given by

`f=(v)/(\lambda)`

Plugging all the values in the above relation, we get

`\begin{gathered} f=\frac{1500\text{ m/s}}{0.0004\text{ m}} \\ f=3750000\text{ Hz} \\ f=3.75\text{ MHz} \end{gathered}`

Thus, the frequency of the wave is

`3.75\text{ MHz}`
