The parameter in GHz or Gigahertz is the frequency which is equal to 10⁹ of 1 Hz or s⁻¹. To determine its corresponding wavelength, we use the speed of electromagnetic waves. Its speed is the same with the speed of light which is equal to 3*10⁸ m/s. The solution is as follows:

Speed = Frequency*Wavelength

3*10⁸ m/s = (2.90*10⁹ Hz) (Wavelength)

Wavelength = 0.1034 m or 1.034*10⁻¹⁰ nm
