That just means they become one wave- hardly would anyone call that one wave is on top of another- Show a combined water wave to someone and ask him how many waves are there- and I will bet the answer is one- and supposedly this 'freak wave' detail is known to Muhammad not just that oceans have waves? Not to mention no one would see 'layers' of this since the peaks would have combined. I mean they're not working with mathematical graphs of waves in front of them from which they can detect the different 'waves' there- Water waves that combine would look like 1 wave and wouldn't be called on top of another wave not to mention in layers (and depth would still be a useless here)- Do you have evidence that they recognized the phenomenon of 'freak waves' and that they held them to be more than 1 wave- but in layers.. I would be interested to know personally- because if someone asked me I would still call it one wave- by the way 'freak waves' are even more 'detailed' information then I would expect someone from a desert to know- Here is a pic I got from yahoo of a freak wave which is clear: http://inlinethumb24.webshots.com/41815/2266391600103830173S600x600Q85.jpg I only see one wave- frankly- even if it is a mix of 'many waves'- Now I'm reading 'wiki'- http://en.wikipedia.org/wiki/Freak_wave#History Causes of them- still under research it seems- But if those waves combine- what you see is only 1 wave- not layers- even I know how to combine waves on paper- they may be 2 waves in paper- but when you see it- it is only 1 wave- not a layer of waves on top each other. Somewhere encounter of this wave and his statement: http://www.bbc.co.uk/science/horizon/2002/freakwave.shtml "Out of nowhere... a wave twice as high as average. The ship went down like freefall" - you see it in one of the boxes where they give 'highlights' This is exactly how I would describe it- 'a wave'- one huge wave. I wonder if they noted that there were layers of waves? I certainly wouldn't. I'm more than happy to accept this if you want because this is even more detail then waves under waves.... Because now you're saying he knew that a single wave was made up of a collection of waves which were all in layer- not to mention this still wouldn't explain depths- I still see my own simple face value approach to be more appealing/consistent/fully utilizes the passage/logical even though this 'freak wave' thing gives much more level of scientific information then anyone would know certainly even I wouldn't give such a description to something which appears to be one wave. But if this is what you see being mentioned then kudos to you; now just show how this would be known. Peace be unto you Please Register or Log in to view the hidden image!
