(Cwavelength of the wave behind the source, if the siren is moving at 20 m/s, is 1.2 m. B) wayelength of the wave infront of the source, if the siren is moving at 40 m/s is 1m. A siren emits a sinusoidal wave with the frequency 300 Hz. The speed of sound is 340 mls. 6. 3. Then the Awavelength of the waves, if the siren is at rest in the air is 1.13 m. (D)wavelength of the wave infront of the stationary source, if the medium is moving Wi* 20m/s towards the observer is 1m.
