The diagram illustrates refraction angles based on Snell's Law and is an important concept in ultrasound.
Snell's law is as follows:
sin θ1/c1 = sinθ2/c2
- θ1 is the incident angle and θ2 is the refracted angle
- c1 is the speed of propagation in the first material and c2 is the speed of propagation in the second material
Example of possible numerical values are shown in the diagram.
