Estimate the minimum thickness of the oil film

Reference no: EM13545846

A thin film of oil (n = 1.12) is located on smooth, wet pavement. When viewed from a direction perpendicular to the pavement, the film reflects most strongly red light at 640 nm and reflects no light at 427 nm. What is the minimum thickness of the oil film?
