In wave physics, what apparent frequency shift occurs when a sound source moves toward a stationary observer?
Answer and explanation
Correct answer: B. The observed frequency increases (higher pitch), known as the Doppler effect
- Step 1: In physics under the North Macedonian State Matura syllabus, The Doppler effect compresses wavefronts ahead of a moving source, elevating detected frequency. Answer: The observed frequency increases (higher pitch), known as the Doppler effect. Why not the others: The observed frequency decreases to zero results from an incorrect physical formulation.
