← ScienceWhich outcome occurs when oil floats on water?
A)Thin-film interference creates color bands.✓
B)Water causes increased oil viscosity.
C)Oil rapidly emulsifies under pressure.
D)Complete miscibility eliminates interference effects.
💡 Explanation
Thin-film interference causes the colorful bands seen because light reflects off the top and bottom oil surfaces, causing constructive and destructive interference. This phenomenon creates color bands, therefore the bands appear because of interference rather than emulsification or increased viscosity.
