It can be shown that where is the wavelength of the microwaves and y is the distance defined in Figure 1. The student plots the graph shown in Figure 4. The student estimates the uncertainty in each value of to be 0.025 m and adds error bars to the graph. Determine the maximum gradient Gmax of a line that passes through all the error bars the minimum gradient Gmin of a line that passes through all the error bars. Gmax = ____________________ Gmin = ____________________
