Observations: Pulses and wave motion and Mathematical descriptions of a wave
Assume that the speed of sound in air is 340 m/s for all of these problems unless stated otherwise.
Tell all You have a sinusoidal wave that is described by the function
(a) Say everything you can about this wave. Pay attention to the positive sign in the equation. (b) Draw a y-versus-t graph and a y-versus-x graph for the wave.
