Acoustic waves or sound waves in air

"Radio and light waves" - pull down

Conversion: frequency f → wavelength λ and wavelength → frequency

c = speed of sound waves or light and radio waves
 audio sound frequency Hz wavelength  in meter (m), feet (ft),  centimeter (cm) or inches (") m cm ft  '' ↓ ↓ wavelength in meters (m) audio sound frequency Hz centimeters (cm) feet (ft) inches ('')
 Given the speed of sound c =  m / s     ft / s

Fill out the gray box above and click at the calculation bar of the respective column.
The proposed speed of sound c = 343 m/s or 1125.33 ft/s can be changed here.

The formulas:  c = λ × f       λ = c / f = c × T       f = c / λ

 physical value symbol unit frequency f = 1/T Hz = 1/s wavelength λ m period or cycle duration T = 1/f s wave speed c m/s

Radio and light waves in vacuum

Conversion: frequency f → wavelength λ and wavelength → frequency

If instead of the speed of sound in air c = 343 m/s,
the speed of light c = 299792458 m/s is used, the following conversions apply.

 radio wave frequency Hz wavelength  in meter (m), feet (ft),   centimeter (cm) or inches (") m cm ft  " wavelength in meters (m) radio wave frequency Hz centimeters (cm) feet (ft) inches (")
 Given the speed of radio waves or light c =  m / s     ft / s

The proposed speed of light c = 299792458 m/s or 983571056 ft/s can be changed here.

Wave frequencies in Hz = 1/s and wavelengths in nm = 10-9 m
