Hello

 

I have an important question.

 

When did human understand(find) that different colors are avoided from water in different depths?

 

I don't want to know the exact time , only say it's century plz.

And please tell me the source of your text.

thank you

Avoided is the incorrect word; there's two words used when talking about light and water.

 

penetration: how far does a specific wavelength travel in the water before it's scattered, absorbed, ect.

 

attenuation: the decrease in light(energy or intensity might also work) as you travel down the water collumn because of scattering, absorbtion, ect.

 

As for your question, i don't know. I'm not that far in my oceanography studies, nor does my power points from my oceanography class that I have on my computer mention dates.

 

I hope I don't sound like an a$$...it wasn't my intention
