this is a very cool physics phenomenon. i just became aware of this.

when light falls through a rippled surface, such as waves on the water, the light rays get refracted in different directions.

if these rays then meet, they make a very bright area. which is what we can see in the video, at the sea floor.

here's some more pics:

This very succinctly explained how they work. I understood them beforehand but not truly the how of it, thanks
