Resources: The Spectacular Spectrum - Separating Light

• Energy and Its Transformation: Electromagnetic Spectrum - FCPS Promotion Benchmark 12 Lesson Review
• The Electromagnetic Spectrum (similar graphic, oriented vertically). See also, Electromagnetic Spectrum (page 3 of 3).
• NASA Mission : Science Tour of the Electromagnetic Spectrum
• Frequency Wavelength Converter (also available in table form). See also, Distance and Length Converter (also available in table form). [See a related Problem of the Day (P.O.D.)].
• Part 1: Exploring the Spectrum
  1. Visible spectrum of white light (sometimes called a continuous spectrum, which technically does not exist)
  2. What is a diffraction grating?
  3. What is a nanometer? 1 nanometer equals 1.0 x 10^-9 meter [0.000 000 001 m (a billionth of a meter), or 0.000 000 1 cm]
  4. Examine the Sun at different wavelengths; Observe an exploded star at different wavelengths ["Application," p. 49, Question No. 6]
  5. What is a laser? (from NASA, The Space Place) ["Application," p. 49, Question No. 7]
• Part 2: Spread the Light
  1. Emission spectrum (sometimes called a "bright line" spectrum)
  2. What is a spectrometer (or spectroscope)?
  3. What is an Ångström? See also, Ångström. 1 nanometer (nm) equals 10 ångströms (Å).
  4. Spectral Lines (See section entitled, "Pick an element from the menu to see its spectral signature."). See also, Visualization of element spectra (National Institute of Standards and Technology).
  5. What is a black light? See also, How Black Lights Work.
• Part 3: Seeing Stars
  1. Absorption spectrum
  2. Astronomical spectroscopy
  3. Flame Tests: Which Ion Causes the Color? (JCE Classroom Activity No. 67). See also, Flame Tests and Chemistry of Firework Colors.
  4. Spectroscopy: Element Identification and Emission Spectra
• Enrichment: Compare the sizes of the wavelengths of the electromagnetic spectrum to the sizes of everyday objects. See Orders of magnitude (length), featuring an external link to Secret Worlds: The Universe Within, a Java animation that presents the notion of scale from the galaxy (10 million light years, 10²³ m) to the quark (100 attometers, 10^-16 m), Molecular Expressions, State University of Florida.
