State the solution formula for the Cauchy problem for the homogeneous wave equation on R3. Prove that solutions corresponding to a localized initial signal (i.e. initial position and derivative are supported in a small ball) have a wave fore front and a wave back front and that these fronts are close to each other. Conclude that music is possible in R3. Say in words what happens if we consider R2 instead.
