Power Reflection and Transmission Coefficients Equilibrium Density
1 Medium - Normal Incidence Equilibrium Density
Boundary Conditions Rigid Wall Free Boundary
Rigid Wall Pressure Doubling
Free Boundary – Pressure Release
2 Medium - Normal Incidence Equilibrium Density x = 0 Boundary Conditions at x = 0
2 Medium - Normal Incidence Equilibrium Density x = 0
3 Medium - Normal Incidence x = 0x = L
3 Medium - Normal Incidence x = 0x = L
Oblique Incidence x = 0
Law of Reflection and Refraction
Reflection Coefficient
Refraction and the Critical Angle What if c 1 > c 2 ? What if c 1 < c 2 ? Transmitted ray bends towards the normal Transmitted ray bends away from the normal
At the critical angle
Angle of Intromission Perfect Transmission –> R = 0
c 2 /c 1 =0.9 r 2 /r 1 =0.9 Book looks wrong!! See pg 158
c 2 /c 1 =0.9 r 2 /r 1 =1.1 Note Angle of Intromission
c 2 /c 1 =1.1 r 2 /r 1 =1.1 Note Critical Angle
c 2 /c 1 =1.1 r 2 /r 1 =0.9

What is B? Look at P(R=2R 1 ) What is pressure at great distances from source?
