Name: The Electromagnetic Spectrum
ID: m42444
Language: English (en)
Summary:
  • List three “rules of thumb” that apply to the different frequencies along the electromagnetic spectrum.
  • Explain why the higher the frequency, the shorter the wavelength of an electromagnetic wave.
  • Draw a simplified electromagnetic spectrum, indicating the relative positions, frequencies, and spacing of the different types of radiation bands.
  • List and explain the different methods by which electromagnetic waves are produced across the spectrum.
