Question

Let us assume that a wave propagates in the direction perpendicular to the flat surface of discontinuity. When the characteristic impedance of the medium of medium 0 (where the incident and reflected wave exists) is much larger than medium 1 (where the transmitted wave exists.), how do the pressure and intensity reflection and transmission coefficient behave? Choose all true statements.

1)Pressure transmission coefficient goes to 2, which means transmitted wave is doubled compared with incident wave.

2)Power transmission coefficient goes to zero, which means no power is transmitted.

3)Power reflection coefficient goes to zero, which means no power is reflected.

4)Pressure transmission coefficient goes to zero, which means no pressure is transmitted.

5)Pressure reflection coefficient goes to 1, which means reflected wave has same sign and magnitude with incident wave.
