f. Use your answers from parts d and e to write equations that can be used to determine the angle(s) for which there will be: - lines of maximum constructive interference - nodal lines g. Determine the angles for which there will be nodal lines and lines of maximum constructive interference for the case of two sources in phase, a distance 1.5λ apart. i. Use your results to draw accurate nodal lines and lines of maximum constructive interference on the diagram at right. ii. Label each line from part i with the corresponding value of ΔD and θ. iii. If the distance between the sources were increased, would the angle θ to the first nodal line increase, decrease, or stay the same? Explain your reasoning.
