Study Notes
Spectroscopy: Studying Light to Understand Matter
- Spectroscopy is a technique used to study light emitted from or passing through materials
- Different types of matter produce or change light in unique ways
- By analyzing these changes, scientists can identify the composition of materials, including stars, planets, and gases.
- The technique compares how the light changes to a "recipe" or proportion of materials present.
Quantum Mechanics and Atoms
- All ordinary matter is composed of atoms, the smallest units of an element.
- Elements are the simplest substances not easily separated.
- Atoms are composed of a nucleus containing protons and neutrons (nucleons) with orbiting electrons.
- The number of protons determines the element.
- Atoms are mostly empty space: nucleons are far heavier than electrons.
Electron Orbits and Energy Levels
- Electrons don't orbit like planets, but the idea helps understand electron behavior.
- Electrons can occupy specific energy levels/orbits.
- Electrons can jump between orbits if energy packets (photons) are absorbed or released
- Higher orbits are farther from the nucleus; lower orbits closer.
Photons and Light Colors
- Photons are the smallest units of light energy.
- Each atom has preferred photon wavelengths (colors).
- Wavelengths of light determine its color.
- Visible light is a small portion of the overall range of light.
- Light acts as both a particle (photon) and a wave.
Continuous and Absorption Spectra
- A continuous spectrum shows all wavelengths/colors.
- Some wavelengths may be missing in certain spectra (absorption lines).
- Absorption lines indicate wavelengths absorbed by atoms in intervening material.
Emission Spectra
- Release of photons causes bright emission lines in spectra when electrons move from higher to lower energy levels.
- Emission lines identify the chemical elements, similar to absorption lines.
Spectroscopy's Applications in Space
- Scientists use spectroscopy to determine the composition of astronomical objects (stars, planets, etc).
- The GIFTS spectrometer, on the Earth Observing 3 mission, will study Earth's atmosphere.
- Detailed atmospheric measurements will be critical to weather forecasting.
Identifying Elements Through Spectra
- Absorption spectra can be used to identify elements by their unique patterns of absorption lines.
- The wavelength and position of these lines identify unique elements.
