Wavelength and Frequency

All waves, including light and sound, have a wavelength and a frequency related to their speed of propagation. The wave speed (v) is constant for a given medium.

  • Wavelength (Ξ»): The distance between consecutive peaks of a wave (meters).
  • Frequency (f): The number of wave cycles per second (Hertz).
  • Wave Speed (v): For light in a vacuum, this is approx. 3 Γ— 10⁸ m/s.

Formula: v = f Γ— Ξ»
