← ScienceWhich phenomenon causes chromatic aberration in refractive lenses?
A)Wavelength-dependent refractive index✓
B)Surface imperfections scattering light
C)Internal material stress birefringence
D)Polarization filtering unequal wavelengths
💡 Explanation
Chromatic aberration happens because refraction angle varies depending on the light's wavelength, therefore different colors focus at different points, displaying blurred images. This Wavelength-dependent refractive index causes dispersion rather than other imperfections in manufacturing.
