we have falling problem inside the tank. We have a fish here. Fish here, the parent depth off the fish Here, the bad in depth off the fish here is given. And ah, the rial depth off the fishies somewhere here. Uh, so this is the real depth. We call this real depth, and the angle we have here is this one and this one here. So the angle from in this part of this partisan angle to we call it that the two and from here to here we call it angle one. Then we have incident angle here, So incident angle, We call it later. So this folly then we could write that that ah tainted the one isn't called to derive a one point to five meters they don't want will be called to staying in worse off 1.1 point six. This gives us 57 point my nine degrees. So this is our angle. They don't want from here using a snows law. In one sign that one is into signed there too. And one is a cooked one. We're in too physical to 1.333 and that no one is 57 point 57.99 degrees. Then that, too, is completed there to score ladies or swallowing. So signed 50 say 1.99 from the cousin. That reward that is a good off one for 333 scientists, too, then solid for a tattoo to visit was signed in Warsaw. Little 1636 Moon. This gives us 39.5 degrees. From here, we can find that the two musicals to derided by the real depth, real depth and the real depth Soling for real dipped real duct is equal to to the right by saying 39.5. This gives US Legal Dept. Off two point 14 meter for the fish.
