soap film वाक्य

For example, the colours seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film.
In contrast, a vertical soap film is affected by gravity and so the liquid tends to drain, causing the soap film to thin at the top.
For this reason, ( open ) soap films of small size are minimal surfaces ( small size reduces gravity effects, and openness prevents pressure from building up.
Such scale models often employed stocking material or tights, or soap film, as they behave in a very similar way to structural fabrics ( they cannot carry shear ).
To continue the physical analogy of soap film given above, these Goldschmidt solutions can be visualized as instances in which the soap film breaks as the circular wires are stretched apart.

With an experiment of soap film and a short glass fiber, mathematicians at New York University have worked out some underlying principles of how something like a willow tree withstands powerful gusts.
By the Young Laplace equation the curvature of a soap film is proportional to the difference in pressure between the sides : if it is zero, the membrane has zero mean curvature.
Physical models of area-minimizing minimal surfaces can be made by dipping a wire frame into a soap solution, forming a soap film, which is a minimal surface whose boundary is the wire frame.
The question as to whether a minimal surface with given boundary exists is called Plateau's problem after the Belgian physicist Joseph Plateau who carried out experiments on soap films in the mid-nineteenth century.
