  1. Electromagnetic Spectrum Mr. Skirbst Physical Science Topic 22

  2. Electromagnetic Waves Wave – a traveling disturbance that carries energy from place to place

  3. Electromagnetic Waves Wave Characteristics –

  4. Electromagnetic Waves Electromagnetic Wave – wave in which electric and magnetic fields carry energy

  5. Electromagnetic Waves Transverse Wave - electric and magnetic fields travel at right angles

  6. Electromagnetic Spectrum arrangement of electromagnetic waves in order of their wavelengths & frequencies

  7. Electromagnetic Spectrum

  8. Visible Light energy released within the range of visible light portion of the electromagnetic spectrum

  9. Visible Light visible spectrum:

  10. Visible Light 3 Types of visible light: • Incandescent – produced from heat • Fluorescent – UV light makes phosphors glow • Neon – energized gas

  11. Spectral Analysis Spectral lines – characteristic wavelengths of light (fingerprint) emitted by a luminous body * Used to identify elements

  12. Spectral Analysis Spectroscope – instrument used to observe spectral lines

  13. Spectral Analysis
