WebThe bright colors seen in an oil slick floating on water or in a sunlit soap bubble are caused by interference. The brightest colors are those that interfere constructively. This interference is between light reflected from different surfaces of a thin film; thus, the effect is known as thin film interference. As noticed before, interference ...

WebThe Mathematics of Constructive and Destructive Interference. Consider a thin film, such as a soap bubble, modelled as a very thin, parallel-sided rectangle, with thickness d and refractive index higher than that of the surrounding air, i.e. n > 1. If the thin film is sitting on top of a different denser medium e.g. water then the following situations will not apply … WebThe phenomenon of Thin film interference provides us an explanation about the occurrence of multiple colors of light from soap bubbles and oil films after reflection. After passing …

Thin-film interference explains the multiple colors seen in light reflected from soap bubbles and oil films on water. It is also the mechanism behind the action of antireflection coatings used on glasses and camera lenses. See more Thin-film interference is a natural phenomenon in which light waves reflected by the upper and lower boundaries of a thin film interfere with one another, either enhancing or reducing the reflected light. When the thickness … See more The type of interference that occurs when light is reflected from a thin film is dependent upon the wavelength and angle of the incident light, … See more Iridescence caused by thin-film interference is a commonly observed phenomenon in nature, being found in a variety of plants and animals. One of the first known studies of this phenomenon was conducted by Robert Hooke in 1665. In Micrographia, … See more • Fowles, Grant R.
