Frequency

• Frequency is the number of waves produced over a given period
• To find frequency, just count the wavelengths
• The frequency and wavelength have an inverse relationship

  • As the frequency increases, the wavelength decreases
  • As the frequency decreases, the wavelength increases
• The units for frequency are Hertz (Hz)
• The higher the frequency, the more energy in the wave
• This wave has high frequency

  
• This wave has low wavelength

  
• Do these waves have high or low frequency?

  A) low

  B) high

  
• Hertz is the number of wavelengths/second
