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.
1 A given atom will absorb and emit the SAME frequencies of electromagnetic (E-M) radiation. 2  A gas of hydrogen atoms will produce an absorption line spectrum if it is between you (your telescope+spectrograph) and a continuum light source, and an emission line spectrum if viewed from a different angle. This is called an emission spectrum (just peaks, not continuous). 2  The E-M radiation frequencies absorbed and emitted match the allowed energy levels in the atom. 3  The allowed energy levels in an atom depend mostly on the electric field configuration.
