And the wavelength of this wave is observed to be 20.3 m. So we can again use wave equation. And according to that the wave speed as frequency times the wavelength

Verified answer

Answer:

[tex]λ \: = \frac{c}{v} [/tex]

[tex]6 = \frac{330}{v} [/tex]

[tex]v = 330 \times 6[/tex]

[tex]frequency = 1980[/tex]
