" Very often too, when sound is reflected, these suppositions will lead to sensibly correct results. On this last account, the problem has here been considered generally for all fluids whether elastic or non-elastic in the usual acceptation of these terms;... "

...reflected sound. If A is the ratio of the density of the second medium to that of the first, and В the ratio of the cotangent of the angle of refraction to the cotangent of the angle of incidence, then the intensity of the reflected sound is to the intensity of the incident as A — 1$ to AtB. In this...
