Would be a good weapon, fire those both mili second apart and when the qaurtz hits a wall it digs itself in (alot of firepower required) and not long after the photons send out a shockwave to eliminate enemies behind cover
potential weapon if we can program FILT to act like this
As for why the PHOT is more dense the closer to the edge of the wave, this is more or less obvious. As the PHOT moves into the QRTZ, the scattering happens deeper and deeper inside, which frees less and less PHOT to the outside. So it thins out the farther in the stacked cluster goes.
E.g., in that first scattering frame, some PHOT is "spawned" outside of the QRTZ. In the next frame, however, the PHOT moves forward, and the scattering spawns it into the QRTZ. But as any medium, QRTZ slows it down. So the first frame PHOT gains an advantage of about one frame and creates a leading wave.
I think I can explain the leading thin wave. Note the effect can be strengthened by centering the QRTZ circle on where the PHOT will hit it, it's one pixel too high. So I moved it one pixel down. Now for what I understand so far: The PHOT stack hits the QRTZ and scatters it around. The scattered wave starts to move in the same frame, and a part of it goes outside of the QRTZ and continues moveing outwards.
So please don't downvote - it's not the scattering that he posted. It's how the scattering works.
I believe the mentioned shockwave is the tiny wave that travels ahead of the rest of the light. Very interesting, I will investigate once on PC.
Most interesting to watch in blob and heat display.
