Wave equation

• Frequency


  The number of complete waves passing a point every second, measured in hertz
• Wavelength


  The distance between two consecutive points on a wave
• Amplitude


  The distance of maximum displacement
• Waves can have frequencies and wavelengths ranging from a thousandth of a millimeter to hundreds of meters
• Calculating wave speed


  Speed = Frequency x Wavelength
• The speed unit must match the units of frequency (per second) and wavelength (centimeters)
• Calculating frequency


  Frequency = Speed / Wavelength
• Frequency is measured in hertz, which means per second
