Small Asteroid Impacts Moon

Layman here. Considering there is no atmosphere on the moon, and stone's conduction properties, does that mean the short flash of light (radiation) was most of the heat energy the impact produced?

You see the part of the spectrum the camera sensor was able to capture. Most of the energy went into displacing/melting the regolith and the shockwave.

There's no shockwave since there's no air on the Moon.

There can be a shockwave along the surface, I suppose, for example.

Could there be a shockwave through the Moon itself?

Possibly, since the regolith is a good conductor.

I meant in the regolith. Can't say if it exceeded the speed of sound in the medium there but given typical impact speeds it probably did. But we can call it a quake if you prefer.

Yes.

There would be no shockwave, just some light and incredible amounts of very localized heat.
