Question: According to your graph, is the relationship between mass density and frequency linear? If not, what is the integer power or root (e.g., x2 , x-1/4) that is closest to your results? If your results are not what you expect, what power do you expect?Question: According to your graph, is the relationship between mass density and frequency linear?
