Checagem de College Physics, 16.3 Simple Harmonic Motion: A Special Periodic Motion
Problema e solução em inglês, como no livro original.
Suppose you pluck a banjo string. You hear a single note that starts out loud and slowly quiets over time. Describe what happens to the sound waves in terms of period, frequency and amplitude as the sound decreases in volume.
Responda com suas palavras antes de olhar.
Frequency and period remain essentially unchanged. Only amplitude decreases as volume decreases.
