 if (sin($F) < 0, 0, sin($F)) ?

or if you regret double sin() evaluation

{
   float s = sin($FF);
   if (s < 0)
      return 0;
   return s;
}

although I don't believe it's a big issue here

…or clamp as mentioned bellow

Hello.
Your question is being a bit complex for doing that by expression.
I create simple HIP file so that you can control attributes of wave via green node.
hope it helps.
