Reflection Coefficient

R = (\frac{v _{2} - v _{1}}{v _{2} + v _{1}})^{2}

Fraction of wave power reflected at boundary between two media.

Variables

Reflection coefficient

Fraction of power reflected (0-1)

unitless

v₁

Wave speed in medium 1

Incident medium

m/s

v₂

Wave speed in medium 2

Transmitted medium

m/s

From continuity of displacement and force at boundary. R = ((Z₂-Z₁)/(Z₂+Z₁))² where Z = ρv.
