3 cards from this section. Quick, good the night before a test.
What happens to a wave at a boundary between two different media?
Think about how energy moves at barriers.
Define mechanical impedance.
It is related to how easily a wave travels through a medium.
What does the reflection coefficient R represent?
Remember, it's about what happens to the wave energy!
True or False: If Z1 = Z2, then there is no reflection.
Think about how same media interact.
A wave takes 50% of its energy into a second medium with impedance Z2 = 30. What is Z1 if R = 0.5?
Use the formula provided to derive Z1.
Explain how the concept of wave transmission at a boundary is applied in telecommunication.
Connect the concept to practical technologies such as fiber optics.
