Light shockwave effect

Hey. Can anyone point me in the direction of possible solutions, please?

I have an object colliding with another. I’d like, upon impact, to emanate a flat circular light shockwave effect that sort of pulsates out towards the camera. I have the objects moving and colliding, I just need help with understanding how to make light, or something similar, move out from within the object in this way.

I’m new to all this and struggling to find a possible way to go about this. Thanks in advance!
