Answer to Question #21460 in Mechanics | Relativity for Gaurav
in case of a wave ,prove that v=1/T, where v is the frequency and T is time period of the pendulum.
in case of a wave ,prove that f=1/T, where f is the frequency and T is time period of the pendulum.
Frequency is the number of occurrences of a repeating event per unit time. The period is the duration of one cycle in a repeating event, so the period is the reciprocal of the frequency. For periodic waves, frequency has an inverse relationship to the concept of wavelength; simply, frequency is inversely proportional to wavelength λ:
f = v/λ.
On the other hand, the phase velocity of a wave is the rate at which the phase of the wave propagates in space:
