Lecture 9 Flashcards
1
Q
Reflection between 2 different boundaries depends on
A
Acoustic impedance mismatch (net impedance)
2
Q
In oblique incidence a single pulse will have
A
Incident pulse, reflected pulse, transmitted pulse
3
Q
3 angle measures to consider in oblique incidence
A
Angle of incidence, reflection, and transmission
4
Q
The transmitted angle changes based on
A
The difference in c (propogation speed)
5
Q
The transmitted angle is the
A
Refraction angle
6
Q
The angle the of the intial beam hitting the median difference
A
Incidence angle
7
Q
The angle of the beam the absorbs into new medium
A
Transmission angle
8
Q
If c1>c2 then the angles….
A
C1 angle > C2 angle
