Answer:

The number of oscillations of the density of the medium at a place per unit time is called the frequency of the sound wave.

Explanation:

The time period of the sound wave T = time taken to complete one oscillation

= 12s / 30 = 0.4 s

The frequency of the sound wave is v = 1/T

= 1 / 0.4s

= 2.5 Hz
