Wave Notes

Rhythmic disturbance that carries energy
Distance between a point on a wave and the identical point on the next wave.
Time required for one wavelength to pass
Number of waves passing per second. The unit of measure is hertz (Hz).
Greatest distance of a wave's rise or fall
Transverse Wave
The disturbance is perpendicular to the direction of wave travel
Longitudinal Wave (Compression Wave)
The disturbance is parallel to the direction of wave travel
Wave Velocity
Wave velocity is the distance a wave travels per second.
velocity / frequency
  • λ = velocity / frequency
  • Example:
    • The musical note middle C has a frequency = 262 Hz. The velocity of sound in air is 343 m/s.
    • λ = velocity / frequency
    • wavelength = 343 m/s / 262 Hz = 1.31 meters
  • velocity = wavelength x frequency
