An ambulance is traveling east at 51.6 m/s. Behind it, there is a car traveling in the same direction at 32.3 m/s. The ambulance driver hears his siren at a frequency of 615 Hz.

- 32.3 m/s Car
- 51.6 m/s Ambulance

What is the wavelength of the sound of the ambulance’s siren if you are standing at the position of the car? The velocity of sound in air is 343 m/s.

Answer in units of meters.

Answer (2)

The wavelength of the ambulance's siren at the position of the car is calculated using the formula λ = v / f, where v is the speed of sound (343 m/s) and f is the frequency of the siren (615 Hz). The result is approximately 0.558 meters. ;
