Many of us are wondering what happens if dark spots begin to envelop a big and bright bubble. Experts have already zoomed in on the answer. When a bubble’s surface transcends from colorful to black, it is about to pop, as researched by physicist Li Shen of Imperial College London.
When a bubble is made, one can notice that its surface is made of thick regions of various hues. The different colors of a bubble serve as a reflection of light rays. On the other hand, the thinnest region is dominated by a black surface.
A phenomenon occurs when the top and bottom light rays of a bubble emerges. It amplifies particular wavelengths called ‘constructive interference.’ The thicker the film, the longer a bubble’s wavelength colors are. The soap film flows and creates pattern shifting because of gravity which makes the bubble bursts.As the wavelengths of light become shorter, the film becomes thinner. This is when dark spots begin to appear larger. Destructive interference casts off light reflections from a bubble’s surface. Li Shen reported this discovery to the American Physical Society’s Division of Fluid Dynamics during a conference in Portland, Ore, according to Science News
Soap Bubbles are thin sheets of water pressed in the middle of two layers of soap molecules. A bubble of air is surrounded by films of soapy water. One end of the molecule attracts water while the other one repels it. These molecules move in and out of a bubble’s surface. Without the presence of these molecules, bubbles will not be able to sustain itself and constantly break into water droplets. Bubbles become spherical because of surface tension.
Soap bubbles may be tapped as the ‘future’ of screen technology. It can serve as the main material in creating thinner and more transparent screens. As claimed by Japanese scientists Yoichi Ochiai, Keisuke Toyoshima, and Alexis Oyama, the colloidal liquid bubble screen's membrane can project images like a typical projector screen.
