What Is Spectroscopy
Question
In the course outline image, what does Spectroscopy mean?
Short Answer
Spectroscopy means spectroscopy, or in Chinese, 光谱学.
In the course outline, Wave Optics: Spectroscopy means the spectroscopy part of wave optics.
Core Idea
Spectroscopy studies:
- how light interacts with matter
- how light is distributed over wavelength or frequency
- how material properties can be inferred from a measured spectrum
A practical intuition is:
- split light into different wavelengths
- inspect the distribution
- use that structure to learn something about the source or the material
Common Related Terms
- spectrum
- wavelength
- frequency
- prism
- diffraction grating
- emission spectrum
- absorption spectrum
Why It Matters In Optics
In optics, spectroscopy is important because wave phenomena such as interference and diffraction make it possible to separate and analyze different wavelengths of light.
Counterpoints and Gaps
- this note explains the meaning of the term only; it does not yet distinguish among the main branches of spectroscopy
- it also does not yet explain how spectroscopy connects in detail to Fabry-Perot interference or grating resolution
