Write the equation of the relation between wave speed,wavelength,and time period.

(N/A) The wave speed $(v)$ is defined as the distance traveled by the wave per unit time.
For a periodic wave,the distance traveled in one time period $(T)$ is equal to one wavelength $(\lambda)$.
Therefore,the wave speed is given by the ratio of wavelength to time period:
$v = \frac{\lambda}{T}$
where:
$v$ = wave speed
$\lambda$ = wavelength
$T$ = time period
