← ScienceWhich consequence results when birefringent material thickness varies in polarimetry?
A)Elliptical polarization changes color✓
B)Refractive index reaches limits
C)Destructive interference prevents transmission
D)Fresnel drag completely compensates shifts
💡 Explanation
Changes in thickness of a birefringent material causes a varying phase shift between orthogonal polarization components; therefore, the output polarization state changes, which manifests as color change due to wavelength-dependent retardation effect, rather than altered refraction.
