$A=$ Dimensionally incorrect.

Time $(sec)$

Please check the type or dimension of your

unit.

$($d$)$ What is the frequency of the tone produced by the transducer? Give your answer in kHz and MHz $.$

$f=,kHzx=$

$MHz$

C$.$ Sound Speed in the Russian Dressing. In ultrasound, wave speed is often given or calculated in units of $"$mm$/s".$

$($e$)$ Use the wavelength in mm $,$ and the period in $s,$ to calculate the wave speed in the dressing in units of $m\frac{m}{}s.$

$C_{dressing}=\frac{{}_{dressing}}{T}=$

$$

$\frac{mm}{{\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}s}=m\frac{m}{}s$

$q,$

D$.$ Sound Speed in the Air.

$($f$)$ Find the speed of the sound wave in air in $\frac{m}{s},$ then convert your result $m\frac{m}{}s.$

$C_{\text{a}\text{i}\text{r}}=\frac{m}{s}=m\frac{m}{}s$

$($g$)$ What is the wavelength of the sound wave in the air of the room?

${}_{\text{a}\text{i}\text{r}}=$
