• A)any two wavelengths
• B)any two wavelengths that are nearly the same
• C)two wavelengths for which lines of the same order are separated by 1\(\pi\) radians
• D)two wavelengths for which lines of the same order are separated by 2 \(\pi\) radians
• E)two wavelengths for which lines of the same order are separated by half the width of a maximum
