Write the definition and dimensional formula of frequency.
(N/A) Definition: The frequency of a wave is defined as the number of oscillations or cycles completed by a particle in a medium per unit time.
It is the reciprocal of the time period $(T)$.
Formula: $f = \frac{1}{T}$.
Dimensional Formula: Since the dimension of time $(T)$ is $[T^1]$,the dimensional formula for frequency $(f)$ is $[T^{-1}]$ or $[M^0 L^0 T^{-1}]$.
It is the reciprocal of the time period $(T)$.
Formula: $f = \frac{1}{T}$.
Dimensional Formula: Since the dimension of time $(T)$ is $[T^1]$,the dimensional formula for frequency $(f)$ is $[T^{-1}]$ or $[M^0 L^0 T^{-1}]$.
