vacate order. Adopted Rules: Closed to Comments. The New York City Environmental Control Board (âECBâ) has modified the ECB Buildings Penalty Schedule to reflect the 2014 updates to the NYC Construction Codes and to more clearly and effectively allow the New York City Department of Buildings (âDOBâ) to enforce particular sections of law.
spectrum-an ordered array of the components of an emission or wave. spectrum line-an isolated component of a spectrum formed by radiation at a uniform frequency. array-an orderly arrangement; an array of troops in battle order. absorption spectrum-the spectrum of electromagnetic radiation that has passed through a medium that absorbed radiation of certain wavelengths.
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.Spectral lines are often used to identify atoms and molecules from their characteristic spectral lines.n absorption line is produced when photons from a hot, broad spectrum source pass through a cold material. The intensity of light, over a narrow frequency range, is reduced due to absorption by the material and re-emission in random directions.
