Unformatted text preview: Draw the path lengths from points A and B to the maximum at point C . Illustrate the path length difference and explain its significance. How far apart are the chains in the beta sheet spaced? Path length difference The path length difference determines the type of interference. Because point C is a maximum, the interference type is constructive. Because point C is the first maximum besides the center, the path lengths must differ by one wavelength. The space between the two sources A and B is the distance between beta sheets.
