This study guide covers the Doppler effect, focusing on the qualitative relationship between the relative motion of a wave source and observer, and the change in observed frequency. Key concepts include rest frequency, observed frequency, and how the direction of motion (approaching or receding) affects the perceived frequency shift. Real-world applications like radar guns, astronomy, and medical ultrasound are also discussed.
