• Acoustic waves or sound waves in air •
"Radio and light waves" - pull down
Conversion: frequency f → wavelength λ and wavelength → frequencyc = speed of sound waves or light and radio waves
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
|frequency||f = 1/T||Hz = 1/s|
|T = 1/f||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.
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
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.
