Calculation:
period, cycle duration, periodic time T to frequency f
and frequency f to period T
frequency  Hz     period  ms
 
period  ms   frequency  Hz

Fill out the gray box above and click at the calculation bar of the respective column.

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

Formulas around the wavelength:

c = λ × f       λ = c / f       f = c / λ

Speed of sound c = 343 m/s at 20 °C and speed of radio waves and light c = 299,792,458 m/s

Conversion: Frequency to wavelength and vice versa
