A sound wave coming from a tuba has a wavelength of 0.674 m and travels to your ears at a speed of 345 m/s.What is the frequency of the sound you hear?
A) 512 Hz
B) 1/517 Hz
C) 230 Hz
D) 1/230 Hz

Question

Quizplus · Accepted Answer

The frequency of a wave is given by the equation f = v/λ, where f is the frequency, v is the speed of the wave, and λ is the wavelength. In this case, the speed of the wave is 345 m/s and the wavelength is 0.674 m, so the frequency is f = 345 m/s / 0.674 m = 512 Hz.
