# Does Amp=0 imply that a wave has 0 speed?

## Homework Statement

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

## Homework Equations

V=F(lambda) E=kA^2

## 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.

thank you.
