Wavelength-Frequency Relationship

The fundamental relationship between wavelength and frequency is essential for all RF calculations. This formula connects the physical size of electromagnetic waves to their frequency.

\lambda = \frac{c}{f}

Alternative Forms

Frequency Form

f = \frac{c}{\lambda}

Solving for frequency given wavelength

Practical Units

\lambda_{m} = \frac{300}{f_{MHz}}

Wavelength in meters, frequency in MHz
