9 waves in 6 minutesWhat is their frequency?

Chapter 2 recap

  • Amplitude (A): the maximum displacement from the equilibrium position. Wavelength (λ): the distance between two corresponding points in phase, e.g. crest to crest. Both in metres.
  • Period (T): the time for one complete wave (s). Frequency (f): complete waves per second (Hz). T = 1/f and f = N/t.
  • v = fλ. Convert prefixes (mega × 10⁶, micro × 10⁻⁶, nano × 10⁻⁹) first. At the same speed, higher frequency → shorter wavelength.
