Study Notes
Spectroscopy
- Spectroscopy is the branch of physics that deals with the investigations of wavelength and intensities of electromagnetic radiation emitted or absorbed by atoms.
Dispersion of Light
- Dispersion of light is the separation of ordinary white light into its components by the use of prism or grating.
Types of Spectra
- Line spectrum is produced when radiations emitted from a hydrogen-filled discharge tube show a series of bright lines at specific wavelengths.
- Atomic spectra is produced by an atom, consisting of a set of discrete lines corresponding to specific energy transitions.
- Continuous spectrum is produced by an incandescent solid, for example, the spectrum of light emitted by a white-hot iron filament.
