Returning to yellow light, what happens to the spacing of the nodal lines if you move the light sources farther apart (say, moving the "Spacing" to the mid point of the slider). What can you say about the dependence of the angular separation of the nodal lines on the spacing of the sources? A. The angular spacing of the nodal lines is inversely proportional to the spacing of the light sources.
B. The angular spacing of the nodal lines is proportional to the spacing of the light sources.
C. The angular spacing of the nodal lines is independent of the spacing of the light sources.
