Explanation
When a sound wave moves from one medium to another, the quantity that remains the same is its frequency.
The frequency of a sound wave is determined by the source of the sound and doesn't change when it enters a different medium.
However, the wavelength and speed of the wave can change depending on the properties of the new medium.
