Why does an ambulance sound louder as it approaches you? This has nothing to do with wavelengths. ONLY FREQUENCY
The ambulance compresses air in front of it as it moves causing sound waves with a lower observed frequency.
The ambulance compresses air in front of it as it moves causing sound waves with a higher observed frequency.
The ambulance compresses air in front of it causing sound waves with longer observed wavelengths.
The ambulance compresses air in front of it causing sound waves with shorter observed wavelengths.
Why do the sound waves in the front look different than the sound waves in the back? NOTHING TO DO WITH WAVELENGTH
The observed waves in front have a longer wavelength and produce a higher pitch.
