I have been asked to "state snells law"

I know the equation is

sin i / sin r = n2/n1

And I know how to use it...

But is there a written law for this that I'm missing? (As in Newtons third law of motion states that.....?)

well explain in words what is happening when you use Snells law. And maybe some applications of it.

I don't know the full context of your question, but why wouldn't giving an equation be a form of "stating" a physical law? Assuming that you've defined the symbols used.

I was just wondering if there was a formal statement that I was missing here. My text books indicate that the equation is the law, but you're right, there's nothing wrong with giving it in that form. As usual, many thanks.
