Answer 2

Frequency of given wave is 226 * 10⁻³ Hz or 226 m Hz

Explanation:

We know that frequency, wave length and velocity of a wave relation to one another by following relation

Speed = wavelength * frequency

Given, speed of sound wave = 339 m/s

wavelength of the wave = 1.5 km = 1500 m

=> v = x * f

=> $f= \frac{v}{x}$

=> $f= \frac{339}{1500}$

=> f = 22.6 * 10⁻²

=> f = 226 * 10⁻³ Hz
