The speed of sound in a particular gas is 900 m/s. A sound wave propagating in this material has a wavelength of 15 m. What is the frequency of this sound?
A)30 Hz
B)60 Hz
C)6,800 Hz
D)13,500 Hz

Question

Quizplus · Accepted Answer

The frequency of the sound can be calculated using the formula $f = \frac{v}{\lambda}$, where $f$ is the frequency, $v$ is the speed of sound in the medium, and $\lambda$ is the wavelength. Substituting the given values, $f = \frac{900 \, \text{m/s}}{15 \, \text{m}} = 60 \, \text{Hz}$.
