A sound wave traveling through dry air has a frequency of 15 Hz, a
wavelength of 23 m, and a speed of 345 m/s. When the sound wave passes
through a cloud of ammonia gas, 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 xx.)
A. 22 m/s
B. 420 m/s
C. 350 m/s
D. 9,700 m/s
