My personal engagement is fine with these BTW. How does the density of the water affect the refractive index of water? I'm going to increase density by increasing salt concentration What is the effect of changing tension on fundamental frequency of a string. What is the effect of changing thickness/diameter on fundamental frequency of a string. Do I need multiple graphs? What if I'm not getting any errors? What if there are no published results online to compare with? Reply Link to post Share on other sites More sharing options...
