A point source that is stationary on an x axis emits a sinusoidal sound wave at a
Question:
A point source that is stationary on an x axis emits a sinusoidal sound wave at a frequency of 686 Hz and speed 343 m/s. The wave travels radially outward from the source, causing air molecules to oscillate radially inward and outward. Let us define a wave front as a line that connects points where the air molecules have the maximum, radially outward displacement. At any given instant, the wave fronts are concentric circles that are centered on the source.
(a) Along x, what is the adjacent wave front separation? Next, the source moves along x at a speed of 110m/s, along x, what are the wave front separations
(b) In front of and
(c) Behind the source?
