Question

What is the wavelength of 2.6 million Hz ultrasound as it travels through human tissue ?

Answer 1

The wavelength of ultrasound waves can be given as,

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

The speed of waves in human tissue is 1540 m/s.

Plug in the known values,

`\begin{gathered} \lambda=\frac{1540\text{ m/s}}{(2.6\text{ million Hz)(}\frac{10^6}{1\text{ million}})}(\frac{10^3\text{ mm}}{1\text{ m}}) \\ =0.592\text{ mm} \end{gathered}`

Thus, the wavelength of waves in human tissue is 0.592 m.
