Answer:

Frequency is basically describe as no of seconds in which pendulum swings through the center .

Explanation:

f= 1/T with time measurement we can measure frequency .

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). λ = c / f = wave speed c (m/s) / frequency f (Hz).
