# Frequency - Wavelength Conversion Table

Here is a handy table of frequency values with their equivalent wavelengths in free space (vacuum), calculated to 4 significant figures. The permittivity of free space is ε= 8.854187817 × 10−12 F m−1 and the permeability is µ0 = 4π × 10−7 N/A2

 About RF Cafe Copyright: 1996 - 2024Webmaster:    Kirt Blattenberger,    BSEE - KB3UON RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
