The Gap Band was an American R&B and funk band that rose to fame during the 1970s and 1980s. The band consisted of three brothers: Charlie, Ronnie, and Robert Wilson, along with other members; it was named after streets (Greenwood, Archer, and Pine) in the historic Greenwood neighborhood in the brothers' hometown of Tulsa, Oklahoma. WebAll light is absorbed when the band-gap energy is less than the 1.77-eV (700-nm) limit of the visible spectrum; narrow band-gap semiconductors, such as the lead sulfide galena, therefore absorb all light and are black. This sequence of colourless, yellow, orange, red, and black is the precise range of colours available in pure semiconductors.
