In order for someone to help you, you need to provide the pertinent details. What is "the wave rock". To what article or passage does the question relate?
I would suggest that you work with a tutor, in whatever subject you are asking for help in, so that you can not only answer your question but can also learn how to make a proper inquiry. I don't say this facetiously, as this is a regular issue on Ask An Expert. One has to ask a full question in order to get a proper answer, especially when you are asking us to be "very specific"!
