Terms & Definitions - Module 30
Match the following definitions (or descriptions) to the terms listed below them.
- The intensity of the light that is emitted at different wavelengths by a light-emitting source.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
- A material is heated to a high temperature. Electrons in the material bounce around and light is emitted.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
- An electron is bumped up from a lower energy level to a higher energy level in an atom.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
- A beam of light passes into this instrument and is split up into lines of different colors (or wavelengths).
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
- White light passes through a material, and certain wavelengths are absorbed, resulting in dark lines in the spectrum.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
-
An instrument that produces a beam of light of a single color, and with all the waves in phase.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
-
A material absorbs radiation and atoms are excited to higher energy levels. After a delay the atoms drop down
to lower energy levels and light is emitted.
- Excitation
- Emission Spectrum
- Spectroscope
- Incandescence
- Absorption spectrum
- Fluorescence
- Phosphorescence
- Laser
- A material absorbs radiation and atoms are excited to higher energy levels. Immediately, the atoms drop down
to lower energy levels and light is emitted.
