Question

formula of frecuency

Answer 1

f = c / λ = wave speed c (m/s) /wavelength λ (m). The formula for time is: T (period) = 1 / f (frequency). λ= c / f = wave speed c (m/s) / frequency f (Hz). The unit hertz (Hz) was once called cps = cycles per second.

Answer 2

Hello mate!

Formula of frequency = Velocity/Wavelength

And it's unit is heartz.

Hope this helps you ✌
