Then the reflection and transmission coefficients are τ = 2ZI ZI + ZII, R = ZI − ZII ZI + ZII. We have already discussed the case where the impedances match and the reflection coefficient vanishes. It is also interesting to look at the limits in which R = ± 1.

WebAs a result, we can deduce that light and sound waves both obey the same laws of reflection. The difference is that for the reflection of sound, unlike light, it is not necessary to have a polished surface. Sound can be reflected from any rough surface too. Thus, it just requires any surface or obstacle to be reflected back. WebThe amount of indirect sound that is reflected depends on the acoustic nature of the reflecting surface.
