(a)[4]
Complete Table 10.1 so that, for each wave type, you give: • the method used to produce the wave • whether the wave detected and used to form the image has been absorbed, reflected or transmitted by the internal body structure.
(b(i))[2]
For one wave type moving through tissue, the wave has $72\%$ of its starting intensity after travelling through $6.2\,\text{cm}$ of the tissue. Calculate the linear attenuation coefficient $\mu$ of the tissue for this wave.
(b(ii))[2]
A different wave of the same type as in $\text{(b)(i)}$ travels through $9.3\,\text{cm}$ of the same tissue. Calculate the percentage of the wave’s initial intensity that is attenuated by the tissue.
