Answer:
T= 1/f
Explanation:
The period (T) of a wave is the reciprocal of its frequency (f). So, if the wave speed (v) and frequency (f) are given, you can calculate the period (T) using the formula:
T= 1/f
Alternatively, if you know the wave speed (v) and wavelength (λ), you can calculate the period (T) using the formula:
T= λ / v
