← ScienceWhich consequence results when polychromatic light shines through interferometer?
A)Chromatic dispersion pattern appears✓
B)Increased speckle contrast appears
C)Refractive index homogeneity increases
D)Reduced sensitivity to air turbulence
💡 Explanation
Chromatic dispersion occurs due to wavelength-dependent interference. Different wavelengths undergo different degrees of constructive and destructive interference because of their varying path length differences; therefore a chromatic color separation pattern is observed, rather than speckle, homogeneity, or turbulence resistance.
