Hey guys,
Just need a bit of help with part of a question from Jacaranda.
8. (a) Using the data from table 18.2, calculate the acoustic impedance of:
(i) soft tissue
(ii) bone of density 1600 kg m−3.
(b) Calculate the ratio of the amplitudes of reflected and transmitted ultrasound
traveling from soft tissue to the bone in part (a).
For part a I got (i) 1.63x10^6 and (ii) 6.53 x 10^6
I'm not sure how to do the second part (b) and the answer is 3:2. Any assistance would be appreciated. Thank You.
