## Homework Statement

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?

## Homework Equations

y=f(x+vt)

## 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?
