   1. The problem statement, all variables and given/known data
   
   Will a wave with an amplitude of 0 have any velocity?
   
   2. Relevant 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 .
   
   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.
