Spectroscopy is the is the study of the interaction between matter and radiated energy. 1 Frequently, spectroscopic data is shown as a spectrum, which is a plot of the response (usually absorbance or transmittance), as a function of wavelength or frequency. Devices that measure this radiation are called spectrometers, spectrophotometers, spectrographs or spectral analyzers
Observing color can be related to spectroscopy. Neon lighting is an example. This type of lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon and other noble gases have certain emission frequencies, and therefore specific observable colors. 2
What exactly happens to the molecules when they interact with light? They undergo changes in energy. When light is absorbed, they undergo an increase in energy, and similarly when

The attenuation coefficient is written as either a product of the absorptivity of the attenuator, ε, and the concentration, c, of attenuating species in the material, as it is written above, or a total (absorption and scattering) cross section, σ, and the density, N', of attenuators. 5
The particle in a box phenomenon is explained as follows. In the one dimensional system, the particle can only move back and forth along a straight line. On each end of the line are barriers. The system is defined by the boundary conditions in which the potential energy is infinite at the ends of the line (creating impenetrable walls), and zero (free movement) at any point along the line. This can be written
