Bryn - it’s not the divergence of rays that causes the light to fade down below. Sunlight that has travelled 149 mn km won’t suddenly fall away because of being a few more km.
It’s the absorption of light by water molecules. The attenuation is much more rapid than in air.

Hey Busker,
I understand that but I'm not concerned with how bright the light is. More the 'shimmering' effect of light in water, again, as compared to sunlight coming through a tree canopy.
take care,
bryn
