Most of the energy of the wave will rebound and sweep towards the other pole. (If you analyze the fields, you will find the natural thing for the fields to do at the poles is to change direction and go in the opposite direction.) However, depending on how fast the field (wave) approaches the pole, some of the energy of the core ball-of-light will be lost in the form of photons and ejected balls-of-light. At lower energies, only photons are induced. At some point, if the energy of the wave is high enough, the energy curls around itself and may form an elementary particle.
The ejected particle's "lifetime" will depend on its harmonics. If it is a harmonic particle, then it will survive. If it is a nonharmonic particle, then it will decay. In general, the less harmonic the particle is, then the faster it will decay. A nonharmonic particle may even explode as soon as it is created.
In general, the faster the particle is ejected, the longer it will survive due to higher induced electric, magnetic and gravitational fields. It is almost as if the faster the particle is ejected, the "harder" it is.
What happens with the electric and magnetic fields of the two particles immediately after the smaller particle is induced? The electric and magnetic fields of the two balls-of-light would be almost exactly adjacent to each other and would create a massive repulsing force at this stage. Thus, the smaller of the two objects would be ejected with high velocity.
