Question

Quizplus · Accepted Answer

When gasoline is poured on a wet street, it spreads out into a thin film over the water due to its low surface tension. The wet street provides a reflective surface for the gasoline, creating interference patterns in the reflected light. The water does not chemically bond with gasoline or slow down its evaporation, but it does provide a second reflecting surface that contributes to the interference colors observed. Therefore, the correct answer is D, only the second reflecting surface.
