The frequency of the wave has not changed.
In fact, the frequency of a wave is given by:

where v is the wave's speed and
is the wavelength.
Applying the formula:
- In air, the frequency of the wave is:

- underwater, the frequency of the wave is:

So, the frequency has not changed.
The equilibrium constant will be lowered and the equilibrium will shift to the left if the heat being produced is not removed.
At point C because it is at the lowest position.
