Audit ultrasonic reflections. Calculate the acoustic impedance of two mediums and determine the power reflection and transmission coefficients at their boundary.
When acoustic waves encounter a boundary with a massive impedance mismatch (e.g., air to water), nearly all the energy reflects back (R ~ 99.9%). This is why ultrasound transducers require coupling gel (to match impedance with human skin).
