Question 3

An ultrasound pulse is incident normally at the boundary between muscle tissue ( $M$ ) and a layer of fat tissue ( $F$ ). The physical properties of these tissues are shown in the table below:

	Muscle tissue ( $M$ )	Fat tissue ( $F$ )
Density	$ρ\rho$	$1.25ρ1.25\rho$
Speed of ultrasound	$v$	$1.6 v$

What percentage of the intensity of the ultrasound is reflected at the boundary?

$1.2%1.2\%$

$11.1%11.1\%$

$23.1%23.1\%$

$33.3%33.3\%$
