   No, that's a different setup where the curve is fixed at   
   the boundaries and not periodic, and gives standing waves.   
      
   There is indeed a lot of mathematics on various possible   
   "boundary conditions", but you were asking for a *physics*   
   setup and explanation underling *wave quantisation*...
