Calculation of the wavelength of an acoustic wave
in air when frequency and temperature is known

Enter the given values in the upper gray fields and click 'calculate'.
The calculated answers will be shown in the lower boxes. 20°C = 68°F

Frequency    Hz   Temperature   °C
       
↓                        
       
 Wavelength   cm    Speed of sound   m/s  
Time period   ms  

The wavelength is changing with the changing of the temperature, because the
speed of sound changes with the temperature. The air pressure is irrelevant!

Calculation of the wavelength of radio waves and acoustic waves
Calculation of the speed of sound in humid air (with air pressure)
Calculation speed of sound in air and the temperature

The formulae (formulas):  c = λ × f       λ = c / f = c × λ       f = c / λ

Physical value Symbol Unit Formula
Frequency f = 1/T Hz = 1/s f = c / λ
Wavelength λ m λ = c / f
Time period or
cycle duration		 T = 1/f  s T = λ / c
Wave speed c m/s c = λ × f
