Grumbler, that makes no sense. Please explain what the Russian implies.

Это означает, что солнечный свет проходит через воду (при этом, конечно, частично поглощается). Так же, как он проходит и через стекло = стекло пропускает солнечный свет.
Определенные сорта стекла могут пропускать видимый свет, но не пропускать, например, ультрафиолет.

Would "translucent" be a more correct term?

You should definitely post Water allows sunlight to pass through. But why just sunlight? Water allows LIGHT to pass through.

Why are you asking me?
I can imagine a context where it's essential that it's sunlight.
Light in general can be monochrome or have a narrow spectrum, even IR or UV. For see plants it's important that sunlight goes through, not just some light. But again, sunlight has a very wide spectrum and not all frequencies go through water equally.

Good point. I didn’t think of that - I kept picturing a glass of water.

“Why are you asking me?”
— it was a rhetorical question)))

Я бы спросил, почему лучи, а не свет.

*where it’s essential that it BE sunlight

Hmm... Thanks

Thanks dudes, i wanted to find out the translation, i think i got it, so i can say “hey, i would recommend you to put the anti-sun cream on your body, because sunlight can pull through water and you’ll get a sunburn!

“Hey, I recommend you put on sunscreen – the sun can burn you even under water.”
