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

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.

conversion radio waves - Frequency f to Wavelength &#955 and Wavelength ? to Frequency f - sengpielaudio

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

Conversion of period to frequency and back

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.

Radiofrequency and microwave radiation are both forms of energy called electromagnetic radiation.
Sunshine contains three other forms of electromagnetic radiation: ultraviolet rays, infrared (heat) waves,
and visible light waves. These electromagnetic waves spread in vacuum with speed of light ≈ 300 000 km/s.

The velocity of propagation of electric signals via cables is nearly 2/3
of the speed of light, that means ≈ 200 000 km/s. s means seconds.
