Answer:
f = 1/T
and
λ = c / f
f = c / λ
Step-by-step explanation:
The formula for frequency is: f (frequency) = 1 / T (period).
f = c / λ = wave speed c (m/s) / wavelength λ (m).
The formula for time is: T (period) = 1 / f (frequency).
The formula for wavelength is λ (m) = c / f
λ = c / f = wave speed c (m/s) / frequency f (Hz).
