 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 ε0 = 8.854187817 × 10-12 F m-1
and the permeability is µ0 = 4π × 10-7 N/A2
See
Espresso Engineering Workbook (free) for a calculator.
