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 nitrous oxide, its wavelength changes to 16 m, while its frequency remains the same. What is its new speed? (The equation for the speed of a wave is v= f x 1.)
A. 350 m/s
B. 16 m/s
C. 5,600 m/s
D. 256 m/s​

Answer:

D. 256 m/s

Explanation:

[tex]f[/tex] = Frequency of the wave = [tex]16\ \text{Hz}[/tex]

[tex]\lambda[/tex] = Wavelength = [tex]16\ \text{m}[/tex]

Speed of a wave is given by

[tex]v=f\lambda[/tex]

[tex]\Rightarrow v=16\times 16[/tex]

[tex]\Rightarrow v=256\ \text{m/s}[/tex]

The speed of the wave as it passes through the cloud of nitrous oxide is [tex]256\ \text{m/s}[/tex].
