← ScienceWhich outcome occurs when a thin-film coating's thickness varies?
A)Rainbow interference fringe patterns appear✓
B)Total internal reflection always occurs
C)Brewster's angle remains unaffected
D)Refracted light's wavelength remains constant
💡 Explanation
If the thin-film coating's thickness varies, constructive and destructive interference will produce varying colours. This creates an interference pattern because different colours of light constructively interfere at different thicknesses. Therefore, rainbow fringes appear, rather than uniformly reflected colours.
