could someone explain to me how when an object gets dropped in water, and the resulting waves are made into a photographic plate, how can that photographic plate contain the size and shape of the object that was dropped in the water. i saw this demonstrated, and don't understand it. also, what would happen if you took ocean waves and made them into a photographic plate, what would you see? hope this all makes sense, because it's really interesting to me. I saw this at a science fair a few months ago. I can't find anything on the web, or in my book on holographs. The demonstrator had some photographic plates of the water ripple images, and he demonstrated how the plates, when placed into the holographic laser system, could create the floating image of the object that was dropped into the water. He didn't have any theory as to how it worked, I think he was just showing something that he'd seen before. John
