Answer

Brief Explanations:

The frequency of a sound wave is determined by the source and remains constant when the wave enters a new medium. The speed - wavelength - frequency relationship is $v = f\lambda$, where $v$ is the speed of sound, $f$ is the frequency, and $\lambda$ is the wavelength. If the speed $v$ increases (as the sound travels faster in the new medium) and $f$ is constant, then according to the formula, the wavelength $\lambda$ must increase.

Answer:

C. The frequency stays the same and the wavelength increases.
