Which outcome dominates when thin film thickness variation approaches wavelength?

A)Iridescence becomes spectrally washed-out✓

B)Refraction angles become more predictable

C)Polarization decreases with increasing angle

D)Absorption increases toward shorter wavelengths

💡 Explanation

Iridescence diminishes as film variation blurs constructively and destructively. This occurs because random thickness variations disrupt constructive interference, therefore color purity degrades rather than showing refined spectral reflection due to phase consistency.
