Question

A person looks down at a puddle made of a thin film of gasoline (n = 1.427) floating on top of some water (n=1.333). The surface looks like a swirl of many different colors. a) They note that a portion of the puddle looks cyan to them, which indicates that less red light (4.62 x 1014 Hz) is reaching their eyes compared to green and blue light. What is the minimum thickness of this portion of the gasoline film? ________________________ b) They note that a different portion of the puddle looks blue to them, which indicates that more blue light (6.60 x 1014 Hz) is reaching their eyes compared to red and green light. What is the minimum thickness of this portion of the gasoline film?
