Wavelength (mm)124.9 mm

Wavelength (m) vs Frequency

Frequency-Wavelength Relationship

Formula

wavelength = c / f

c = 299,792,458 m/s (speed of light)

Higher frequency means shorter wavelength. This relationship is fundamental to antenna design, optics, and RF engineering.

Example Calculation

Wi-Fi at 2400 MHz (2.4 GHz).

  1. 01Wavelength = 299.792 / 2400 = 0.1249 m
  2. 02Wavelength = 12.49 cm
  3. 03Wavelength = 124.9 mm
