Question

1. low note = long pipe = _____________ wave

options: short, long, medium

Explanation:

Low musical notes correspond to low frequency sound waves. For a pipe instrument, a long pipe produces a low note because it allows for a longer sound wave wavelength (longer wave) to form inside it, as wavelength and frequency are inversely related ($v = f\lambda$, where $v$ is wave speed, $f$ is frequency, $\lambda$ is wavelength). Lower frequency means longer wavelength.

Answer:

long
