A wave is described by the function 
, where:
is the current offset of the observed point
is the wave amplitude of the oscillating particles of matter
is the wave frequency
is the wave velocity
the distance of the observed point from the source of the wave
is the elapsed time
The wave propagates through a substance, which is described by the equation:
The sketch below is for the performance only, it does not represent the given function:
Obtain the wave frequency and the wave speed .
What is the distance from the wave source to the point that is 36cm farther away after 10 seconds?
What is the displacement of the point located 14cm farther away from the source at the same instant?
