Layer of bubbles on water produced by washing up liquid. The colours,produced just before the bubbles burst,are due to interference between light rays reflected from the front & back of the thin film of water making the bubble. The colours depend on the thickness of the film; black where the film is very thin indeed,silver colours are produced by a film about 70 nanometers thick,gold about 100 nanometers thick,green about 150 nanometers thick & red as the film gets thicker | |
