The pulse is partially transmitted and reflected at the interface where the speed of propagation undergoes a change:

Transmission factor
Note
The transmission factor
| $ T_{12} =\displaystyle\frac{2\sqrt{ Z_1 Z_2 }}{ Z_1 + Z_2 }$ |
can be plotted as a function of the ratio of the impedance in the medium that is transmitted divided by the impedance of the medium from which it comes:

The reflection factor
| $ R_{12} =\displaystyle\frac{ Z_1 - Z_2 }{ Z_1 + Z_2 }$ |
can be plotted as a function of the ratio of the impedance in the medium that is transmitted divided by the impedance of the medium from which it comes:
