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
