Wavelength, Period, and Frequency Lower Frequency Higher Frequency The period of a wave is the time it takes the wave to complete one cycle. The frequency of a wave is the inverse of its period. frequency = 1/ period Frequency is measured in Hertz (Hz). 1 Hz = 1 cycle/second 2-2 Wave Length Wave Length Distance Wave Period Wave Period Time

The frequency of a wave is the inverse of its period. Frequency is measured in Hertz (Hz). frequency = 1/period The relationship between wavelength and frequency gives the speed of a wave: s = f L s = speed at which radiant energy travels (meters/sec or mi/sec) f = frequency (cycles/sec, or Hertz) L = wavelength (in meters or feet) Compare Electromagnetic and Sound Waves Which type of waves can travel through air? Which type of waves can travel through a vacuum? How do the
