Conversion and calculation:
Time period, cycle duration, periodic time T to frequency f,
and frequency f to time period T
The only kinds of periods meant by people who use this phrase are periods of time, so it’s a redundancy. Simply say "time" or "period."

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

The unit hertz [Hz] was once called cycles per second [cps].

Frequency formula

 f = 1 / T and f = c / λ 
Aha!

Formulas and equations around frequency and wavelength

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

Choose: Speed of sound in air c = 343 m/s at 20 °C or
speed of radio waves and light in a vacuum c = 299,792,458 m/s

Sine curve

ω = 2 π f

Conversion: Frequency to wavelength and vice versa
