The displacement of the medium in a sound wave is given by the equation; \( \mathrm{y}_{1}=\mathrm{A} \cos (\mathrm{ax}+\mathrm{bt}) \) where \( \mathrm{A}, \mathrm{a} \& \mathrm{~b} \) are positive constants. The wave is reflected by an obstacle situated at \( \mathrm{x}=0 \). The intensityhttps://bit.ly/YTAI_PWAP https://www.pw.live
