Physics Online Professional Development: The Doppler Effect

Explore the fundamental principles of the Doppler Effect in this professional development course designed for physics educators. Learn how wave frequency changes when there is relative motion between a wave source and observer, examining real-world applications from ambulance sirens to astronomical observations. Master the mathematical relationships governing frequency shifts for both sound and electromagnetic waves, and discover effective teaching strategies for presenting this concept to students. Analyze practical examples including radar technology, medical ultrasound, and redshift in astronomy while developing hands-on demonstrations and laboratory activities. Gain confidence in explaining the underlying physics concepts and addressing common student misconceptions about wave behavior and relative motion.
