The music video was directed by Hong Won-ki of Johnny Bros, who produced numerous hit films such as Girls’ Generation, Mamamoo, (G)I-DLE, and Oh My Girl. Melanie Fontana, in particular, is a singer-songwriter who has made a number of Billboard hits such as Chainsmokers, Justin Bieber and Britney Spears, familiar to Korean fans not only for composing but also for being on one stage with BTS and NBC’s “SNL” in the U.S. SECRET NUMBER’s debut song “Who Diss?” which features more sophisticated and differentiating the members’ individuality, was co-produced by Melanie Fontana, who composed BTS’ “Boy With Luv,” Michel “Lindgren” Schulz and composer Shark. VINE Entertainment on Tuesday unveiled its super-luxury producers who participated in SECRET NUMBER’s debut album, raising expectations for the creation of a fourth-generation talented girl group. New girl group SECRET NUMBER will debut with Producer Avengers.

Rainbow-like colors from closely spaced narrow tracks on optical data storage disks such as CDs or DVDs are an example of light diffraction caused by diffraction gratings. Ī diffraction grating can create "rainbow" colors when it is illuminated by a wide- spectrum (e.g., continuous) light source. Rogers (1804–1882) took over the lead and, by the end of the 19th century, the concave gratings of Henry Augustus Rowland (1848–1901) were the best available. Gratings with the lowest line-distance (d) were created, in the 1860s, by Friedrich Adolph Nobert (1806–1881) in Greifswald then the two Americans Lewis Morris Rutherfurd (1816–1892) and William B. Using these principles, Fraunhofer was the first who used a diffraction grating to obtain line spectra and the first who measured the wavelengths of spectral lines with a diffraction grating. The principles of diffraction were discovered by Thomas Young and Augustin-Jean Fresnel. This was similar to notable German physicist Joseph von Fraunhofer's wire diffraction grating in 1821. The first man-made diffraction grating was made around 1785 by Philadelphia inventor David Rittenhouse, who strung hairs between two finely threaded screws. James Gregory (1638–1675) observed the diffraction patterns caused by a bird feather, which was effectively the first diffraction grating (in a natural form) to be discovered, about a year after Isaac Newton's prism experiments. There are also gratings that modulate the phases of incident waves rather than the amplitude, and these type of gratings can be produced frequently by using holography. Such a grating modulates the amplitude of an incident wave on it to create a diffraction pattern. Butterfly and flowers 1080p HD photos nature.
