Study Notes
Spectrometry
- A method of analysis that deals with the measurement of spectra, including color and electromagnetic (EM) spectra.
Electromagnetic (EM) Spectrum
- Measurement of wavelength in the EM spectrum is crucial.
- Measurement of the power of transmitted, fluorescent, reflected, or emitted energy is also important.
Color and Wavelength
- The transmitted color is the one that is visible to the human eye.
- White light is a combination of all colors.
- Wavenumber is the reciprocal of wavelength.
- Red light has the longest wavelength (outside the visible spectrum).
- Violet light has the shortest wavelength (inside the visible spectrum).
EM Spectrum and Energy
- Shortest wavelength can have the highest energy.
- EM/energy waves produce energy, similar to ocean waves.
Visible Region
- The visible region of the EM spectrum spans from 400-700 nanometers.
- Colorimeter is used in the visible region of the EM spectrum.
