Interfere…

This fabric lends its name to a visual artifact in digital video/imaging. Identify.

PS: apologies for superlate post. Gremlins got my internet connection this time.

Answer:
The so-called “Moire pattern” is named after the Moire fabric. Interference between closely-spaced sets of parallel lines causes the strange patterns that you see very frequently when people wear stripes on TV :-)

Points assigned by AutoRaja. Review by lazy humans pending.

    Did a search and found that the 2nd one is actually an embroidered “faux” Moiré.

    Beautiful question. :)

    In physics, a moiré pattern is an interference pattern created, for example, when two grids are overlaid at an angle, or when they have slightly different mesh sizes.

    The term originates from moiré , a type of textile, traditionally of silk but now also of cotton or synthetic fiber, with a rippled or ‘watered’ appearance.

    Awesome question. Moire patterns from the moire fabric which the dresses are made of that shows a similar rippled appearance.
