A film of oil lies on wet pavement. The refractive index of the oil exceeds that of the water. The film has the minimum nonzero thickness such that it appears dark due to destructive interference when viewed in visible light with wavelength 673 nm in vacuum. Assuming that the visible spectrum extends from 380 to 750 nm, what is the longest visible wavelength (in vacuum) for which the film will appear bright due to constructive interference? please help thank you

When white light illuminates an oil film on water and the reflected light is viewed perpendicular to the surface of the water, no green light at 548 nm is reflected but there is a strong presence of red light with a wavelength of 685 nm. Determine the thickness of the oil film. Take the index of refraction of oil to be 1.28.

A thin film of alcohol (n = 36) lies on a flat glass plate (n = 51). Light whose wavelength can be changed is incident normally on the alcohol. The reflected light is a minimum for l = 512 nm and maximum for l = 640 nm. What is the minimum thickness of the film? 235 nm 94 nm 1412 nm None of the above

A thin film in air is made by putting a thin layer of acetone (n = 1.25) on a layer of water (n = 1.33). When visible light (400nm – 700 nm) shines normally on the film an observed from above, the bright reflected light looks kind of “purplish” with red light of wavelength 650 nm mixed some blue giving it that appearance and “greenish” light of wavelength 520 nm is completely destroyed. Determine the thickness of the acetone film....
