Thread: Whats the maximum amount of water molecules that can fit into your field of vision?

Say your submerged enough so that if you look in one direction, you don't see the surface of the water nor the shore beneath you. What volume of water fits in your view?

Pop it in liters and multiply by Avigadro's number?

Is that..? How much water can I see through ? I will call it a cone shaped wedge of water..

How many litres can I see..? Would be entirely dependant upon the transparency of this water..

I have worked for many years as a soundings engineer..

We lowered equipment to the sea floor and took readings of rock structures.

On the winching of that equipment back onto the ship I saw some of the waters are very clear.

The Atols of the Pacific would contain a greater clarity.

While around the coast of NZ oceanic currents seemed to carry more impurities..

...' So to answer this question a dependency on clarity is apparent..' ...

Near the coast of Samoa and around the sheltered bays of Indonesia I could see through thousands of litres..

while around Sydney Australia I could only see tens of litres.. I do not think a uniform clarity can be found..

This could be why other frequencies are used in water..

Ultra sound transmits better than light. Ask a whale.

When you wish to equate with 'Avigadro's number?' It might be better to be working with gasses..

Counting the number of water molecules per litre.... 10 x to the power of thousands...per cubic mm.

( which is to say..I can not go here..I do not know.)

100% fits into my view

Hilaaaariiioously clever.

and astro,

come on now no need to get cute. The question states, "maximum amount"- so clearly I am referring to fresh water.

so how far does light penetrate into fresh water? If Im in a pool swimming, and I look down, how far does the floor of the pool have to be from me until I can't see it anymore? At that range, whats the volume of water that fits in my field of vision?

I think its a legitimate question. Im not looking for an answer persay, just a sort of brainstorming session of how you would find it out. Thats the beauty- we'll all take seperate roads but arrive at a similar conclusion. I want to know the roads others may take is all.
