1. Complete the last column (Wavelength) in Table 1 using the wave equation (v=fA). Show all of the calculations for the Density of 0.7 kg/m data using scientific investigation guidelines. 2. Plot a scatterplot graph of Speed (cm/s) vs Density (kg/m) in Excel or Google Sheets (using Table 1). The independent variable is density, which must be plotted on the horizontal axis. Insert a POWER trendline and insert the equation and R-squared value. Follow proper scientific investigation guidelines
