SUMMARY
The discussion focuses on calculating the Doppler effect for a car traveling at 30 m/s with a siren frequency of 600 Hz and sound velocity in still air at 330 m/s. The wavelength of sound waves is determined to be 0.05 m when the car is stationary. For the moving car, the wavelength in front is calculated as 0.5 m and behind as 0.6 m using the equations Wavelength behind = (Vm + Us) / Fs and Wavelength in front = (Vm - Us) / Fs. The frequency of the sound heard by a stationary observer can be derived from these wavelengths using the formula V = F * λ.
