A puddle of water is covered with an oil film that has an index of refraction with an unknown value. However, it is known that the unknown value is greater than that of water. The thickness of the oil film is such that it is the minimum thickness possible for normally incident infrared radiation with a wavelength of 836 nm to experience destructive interference in the reflected radiation. When white light is incident normal to the oil film, what wavelengths in the visible range (400 nm-700 nm) will experience constructive interference?

Diffraction of light

In physics, the term diffraction is defined as the bending of light around the corners of the obstacle. As a light ray passes by an aperture, it bends around the edges or through slits, it spreads out through a narrow opening. The diffracted light will produce fringes of bright and dark or colored bands which are labeled as a diffraction pattern.
