If two media have identical impedances, what are the reflection and transmission outcomes?

Explanation:
When a wave reaches a boundary where the two media have the same impedance, there’s no impedance difference to create a reflected wave. The boundary is perfectly matched, so all the incident energy passes into the second medium. The wave may change speed and wavelength to fit the new medium, but there’s no reflection and no loss at the boundary. In other words, there is no reflection and full transmission.
