3. Complete the last column (Wavelength) in Table 2 using the wave equation (v=fA). Show a complete calculation using proper scientific investigation guidelines for the Tension of 3.5 N data. 4. Using either Excel or Google Sheets, plot a scatterplot graph (using Table 2) of Speed (cm/s) vs Tension (N). The independent variable is tension, which must be plotted on the horizontal axis. Insert a POWER trendline and insert the equation and R- squared value. Use proper scientific investigation guidelines
