   The response is:

   Help on built-in function Begin:
   
   Begin(...) method of LightPipes._LightPipes.Init instance
       F = Begin(GridSize, Wavelength, N)
   
       :ref:`Creates a plane wave (phase = 0.0, amplitude = 1.0). <Begin>`
   
       Args::
   
           GridSize: size of the grid
           Wavelength: wavelength of the field
           N: N x N grid points (N must be even)
   
       Returns::
   
           F: N x N square array of complex numbers (1+0j).
   
       Example:
   
       :ref:`Diffraction from a circular aperture <Diffraction>`
   
   >>>
