What is the wavelength of X-Band?

Explanation:
Wavelength is found from λ = c / f, with c about 3×10^8 m/s. X-band covers roughly 8–12 GHz, so at 10 GHz the wavelength is 3×10^8 / 10×10^9 = 0.03 m, which is 3 cm. Therefore, the X-band wavelength is about 2.5–3.75 cm across its typical range, and 3 cm falls right in the middle. For context, 1 cm corresponds to about 30 GHz, 10 cm to about 3 GHz, and 30 cm to about 1 GHz.
