Document Summary

Electromagnetic radiation is made up of magnetic and electric fields oscillating at right angles to one another (3. 1a). Waves are characterized by their wavelength, frequency, and speed (3. 1a). Wavelength and speed are related by the speed of light (3. 1a). The electromagnetic spectrum shows the different types of electromagnetic radiation (3. 1b). Visible light is a small portion of the electromagnetic spectrum (3. 1b). The photoelectric effect suggests that light has particle-like properties (3. 2a). Light travels in packets called photons, and the energy of a photon is related to the wavelength and frequency of the light (3. 2a). Planck"s equation relates the energy of a photon to its frequency (3. 2a). 3. 3 atomic line spectra and the bohr model of atomic structure. When light emitted by excited atoms is passed through a prism, the resulting spectrum is called a line spectrum and is characteristic for a given element (3. 3a).
