  "term": "Thin-film interference",
  "field": "Industrial and trades",
  "definition": "A phenomenon where light waves reflecting from the top and bottom surfaces of a thin film interfere with each other, producing iridescent colors. The constructive or destructive interference depends on the film's thickness, the refractive indices of the film and surrounding media, and the angle of incidence. This effect is responsible for the colors seen in soap bubbles, oil slicks, and anti-reflective coatings.",
