1. Homework Statement

Will a wave with an amplitude of 0 have any velocity?

2. Homework Equations

V=F(lambda) E=kA^2


3. The Attempt at a Solution

I think the wave dissappears because if it carries no energy then it ceases to be a wave, but Im not sure though.

You are correct :approve:.

In a little more detail the solution y(x,t)=0, is the trivial solution of the wave-equation and is not usually considered to be physically meaningful.
