PHYSICAL PROPERTIES OF ELECTROMAGNETIC WAVES​

  •   Wavelength​
  •   Frequency​
  •   Photons

WAVELENGTH​

  • Waves can vary in size. They are measured by the distance between two adjacent peaks or crest.​
  • Wavelength is measured in nanometers (nm).​

FREQUENCY​

  • The frequency of a wave is based on the number of cycles that will pass through space in one second. ​
  • Frequency is measured in Hertz (Hz). The number of waves divided by the number of seconds.  ​
  • Frequency is inversely proportional to wavelength. ​

(ie. longer wavelength = lower frequency)
