1. The problem statement, all variables and given/known data A wave pulse is described by the function y(x,t)=De^-(Bx-Ct)^2, where B, C and D are all positive constants. What is the speed of this wave? 2. Relevant equations y=f(x+vt) 3. The attempt at a solution y=De^-(Bx-Ct)^2 is of the form y=f(x+vt) however there is a B in front of x so I factor the B out and get -(Bx-Ct)^2 = -B^2(x-Ct/B)^2 so the velocity is C/B Is this the right approach?
