Hummer H2 (189.8 in) = 62.2 MHz
Golden Gate Bridge (6,450 ft) = 153 kHz
Earth Equatorial Diameter (7,926 mi) = 23.5 Hz
| Wavelength and frequency are related by the following formula: c = l * u * √er, | where c = speed of light
l = wavelength
u = frequency
er = relative permittivity |
Here are some familiar objects and their
equivalent wavelength-related frequencies in air: 
0402 Surface Mount Capacitor (0.040 in) = 295 GHz
Ticonderoga #2 Wooden Pencil (7.5") = 1.57 GHz
Meter Stick (1 m) = 300 MHz
Boeing 747-400 (231'10") = 4.24 MHz
Channel Tunnel, "Chunnel" (37 km) = 8.10 kHz
