Virginia’s CTE Resource Center

Analyze electromagnetic radiation and the electromagnetic spectrum.


Analysis should
  • explore the relationship between wavelength and frequency across the electromagnetic spectrum
  • include the application of the inverse square law to electromagnetic radiation
  • differentiate between wave theory and particulate theory.

Process/Skill Questions

  • How are wavelength, energy, and frequency related?
  • What is the difference between radio waves and X-rays?
  • How does the frequency for an AM radio station vary from an FM station?
  • When would you apply Planck’s constant?
  • When would you apply Einstein’s theory?
