The study of emission and absorption spectra in relation to element identification and relative motion is called the Absorption spectroscopy. Absorption spectroscopy refers to the study that measures the radiation absorption, in relation to wavelength or frequency, by contact with the sample.

Intensive management unit refers to a prison within a prison for some of the state’s most violent and dangerous offenders.  it is generally defined as holding someone in a cell, typically for 22 to 24 hours a day, with minimal human interaction.
