Wavelength to Frequency Calculator

In radio and electromagnetic theory, frequency and wavelength are two ways of describing the same thing: how energy moves through space. This calculator helps you convert between them using the relationship:

\[ \text{Wavelength (meters)} = \frac{300}{\text{Frequency (MHz)}} \]
or
\[ \text{Frequency (MHz)} = \frac{300}{\text{Wavelength (meters)}} \]

This formula is based on the speed of light in a vacuum (approximately 300 million meters per second). It's widely used in amateur radio and RF design to determine antenna lengths, band coverage, and propagation behavior.

Enter either the frequency (in megahertz) or the wavelength (in meters), and the calculator will give you the corresponding value. This is especially useful for antenna design, where the physical length of an antenna element is often tied directly to the operating frequency.
