1. Pressure Reflection and Transmission Coefficients Equilibrium Density

2. Intensity Reflection and Transmission Coefficients Equilibrium Density

3. Power Reflection and Transmission Coefficients Equilibrium Density

4. 1 Medium - Normal Incidence Equilibrium Density

5. Boundary Conditions Rigid Wall Free Boundary

6. Rigid Wall Pressure Doubling

7. Free Boundary – Pressure Release

8. 2 Medium - Normal Incidence Equilibrium Density x = 0 Boundary Conditions at x = 0

9. 2 Medium - Normal Incidence Equilibrium Density x = 0

10. 3 Medium - Normal Incidence x = 0x = L

11. 3 Medium - Normal Incidence x = 0x = L

12. Oblique Incidence x = 0

13. Law of Reflection and Refraction

14. Reflection Coefficient

15. 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

16. At the critical angle

17. Angle of Intromission Perfect Transmission –> R = 0

18. c 2 /c 1 =0.9 r 2 /r 1 =0.9 Book looks wrong!! See pg 158

19. c 2 /c 1 =0.9 r 2 /r 1 =1.1 Note Angle of Intromission

20. c 2 /c 1 =1.1 r 2 /r 1 =1.1 Note Critical Angle

21. c 2 /c 1 =1.1 r 2 /r 1 =0.9

22. Method of Images d d Rigid boundary z=h

23. Pressure Release Surface d d Pressure release boundary h nulls

24. Free Release/Rigid Boundary

25. Pressure Release Surface z

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