"True" velocities at the end points are v1 = 0 and v2 = 1.2 cm s-1 giving a strain rate of -1.0 s-1 (blue squares), the strain rate is actually the. slope of the line between the points, being equal to (v2 - v1)/L (blue line).

The minus sign is essential for relativistic invariance and leads to propagating solutions (waves). With. φ ( x, t) = exp [ i ω t] ψ ( x). we obtain. ω 2 ψ ( x) = − ∂ x 2 ψ ( x) Since − ∂ x 2 is a non-negative operator, ω 2 ≥ 0.
