Thin Film Interference in a Soap Bubble
Summary
[edit]
| Description |
English: This image shows a lamp's reflection on a soap bubble, revealing a vibrant rainbow pattern resulting from thin film interference. This phenomenon occurs when white light interacts with a thin film, causing partial reflection and refraction. As the light reaches the film's opposite side, it is again partially reflected and refracted. The two reflected light portions then converge and interfere, leading to either constructive or destructive interference under specific conditions. Due to distinct frequencies of different colors, interference varies, and the film's uneven thickness across the bubble allows for diverse constructive interference, forming the rainbow effect. This occurrence is also visible in other thin films, such as oil on water and glass coatings.
To capture this image, a 1:3 dishwashing soap and water mixture was created, with added glycerin to enhance surface tension and prevent the bubble from popping. The final image was cropped without further adjustments. SONY ILCE-6400, 30mm Macro Lens, 1/500s, f/22, ISO 1000. |
