Which behavior is observed when monochromatic light passes through stacked oil films of continuously varying yet extremely small thickness?

💡 Explanation

Alternating fringes appear because constructive and destructive interference varies along wedge thickness gradients. Thin-film interference relies on path differences; therefore we see varying interference, rather than uniform patterns from diffraction or spectral changes from selective absorption.
