Double the frequency of a sound and you halve its
A) wavelength.
B) amplitude.
C) speed.
D) all of these
E) none of these

Question

Quizplus · Accepted Answer

Doubling the frequency of a sound wave halves its wavelength because the speed of sound in a given medium is constant, and frequency and wavelength are inversely related as described by the formula $v = f \lambda$, where $v$ is the speed of sound, $f$ is the frequency, and $\lambda$ is the wavelength.
