Physics is a cumulative subject, so make it sure you understand basic concepts and typical problem solving techniques in previous chapters before moving on to a new chapter! ________________________________________________________________________________ A. Sound Waves & Interference Two identical sources of sound are separated by 1 m, and they emit waves in phase at wavelength of 0.3 m. If we move a sound detector along a large circle centered at the midpoint between the sources, at how many points does the detector detect constructive interference? B. Doppler Effects Passengers in a car traveling at 15 m/s hear a siren with a frequency of 1000 Hz from a fire engine approaching them from behind at a speed of 40 m/s. What frequency do the passengers hear after the fire engine passes them? fire engine passes them?...
