Diffraction & Spectroscopy Quiz

The measure of electric current flowing through a unit area of a material due to the movement of charged particles.

A parameter that describes how a wave propagates through a medium, relates to the wave's speed and frequency.

A mathematical description of how waves, such as light or sound, propagate through space and time.

A vector that signifies the direction of wave propagation and its wavelength.

A method used to measure the absorption or transmission of UV and visible light in solids, liquids, and gases to analyze structures.

A type of interaction where energy is conserved and there is no change in energy state during emission.

An interaction where energy is absorbed or emitted, changing the energy state of particles.

A measure of how much a medium can absorb light per unit length.

E is defined in terms of wave number and attenuation in materials (E=Ex.e^(2πηi/λ)e^(-αχ)).

Absorption per unit length is affected by concentration of the absorbing medium (A= absorption per unit length/per unit concentration).

An interaction where energy is lost during the scattering process.

The decrease in energy quantified during inelastic scattering.

Spectroscopy technique focusing on energy loss of electrons.

Spectroscopy related to the analysis of sputtered particles.

Technique to analyze the elemental composition and electronic states using X-rays.

The change in wavelength of light when scattered by molecules, indicating bond vibrations.

The process where particles or waves are forced to deviate from a straight trajectory.

The shortest wavelength of visible light, used in Raman spectroscopy.

A tool that allows only green light to pass through, used to isolate specific wavelengths.

A person or device that detects and measures the scattered light in an experiment.

A bond between two carbon atoms involving shared electrons.

A double bond between carbon and oxygen resulting in higher energy than a single bond.

An excited state where electrons have absorbed enough energy to move to higher orbitals.

The lowest energy state of an electron in an atom, where it is most stable.

The process by which an electron absorbs energy and moves from a lower to a higher orbital.

Distinct peaks in a Raman spectrum that correspond to different vibrational modes of a molecule.

A technique in spectroscopy that identifies substances based on unique spectral features, similar to human fingerprints.

The measure of how pure and representative a sample is for analysis in spectroscopy.

The tools and devices used for measuring and analyzing spectroscopic data, including sources and detectors.

The process where incident light interacts with molecular vibrations, resulting in scattered light with changed frequency.
