Which outcome dominates when thin oil films produce colors?

💡 Explanation

Constructive interference amplifies certain wavelengths, causing colors because the slightly different path lengths lead to phase shifts that reinforce rather than cancel. Destructive interference diminishes other wavelengths, therefore, colorful patterns, not viscosity, manifest.
