The equation y=As in(wt-kx)represents a
plane wave traveling along the x-direction. If
a=0.10m, w=8500hz and k=25/secs......Calculate
the speed of the Waves
-Calculate the speed of the medium through
which the wave is travelingl -What is the equation of the reflected wave
produced when thisv wave strikes a rigid
boundary normally?
