A sound wave traveling through dry air has a frequency of 16 Hz, a
wavelength of 22 m, and a speed of 350 m/s. When the sound wave passes
through a cloud of methane, its wavelength changes to 28 m, while its
frequency remains the same. What is its new speed? (The equation for the
speed of a wave is v= f x.)
A. 350 m/s
B. 9,800 m/s
C. 450 m/s
D. 13 m/s
