The sound wave speeds up and bends.
the sound wave slows down and bends
Sound waves travel FASTER through water than through air. Since the molecules in water are closer together than the molecules in air, the closeness of these molecules allow sound waves to be carried more efficiently. This is also why sound waves travel fastest in solids because the molecules in solids are tightly packed together, and there is less space in between the molecules. Since there is more space in between the molecules of air, it takes more time for a sound wave to travel.
In addition to the increase in speed, frequency remains unchanged because a change of medium (from air to liquid) does not effect frequency.
The frequency of sound only depends on the source. It doesn't change even when the sound wave travels through different media. Only the speed and wavelength will change. In this case, sound is traveling into a denser medium. So, the speed and the wavelength of the sound wave will increase.
increases
Sound is a wave (of energy) in a medium [solid,liquid, or gas] (a compression wave in fact), therefore it is refracted by any change in the medium AND by the fact that it is never coherent (it never travels in only a straight line).
the wave length of sound increases
It will be like it was before
The cork will move up and down with the wave, since the wave is a transverse wave. I would think that the frequency should be the same as the wave.

The density of air increases and then decreases as the sound wave passes.
it stay at the surface
the wave length of sound increases
what happens to interstellear gas as it passes through a spiral density wave
The speed of the wave increases, the frequency remains constant and the wavelength increases. The angle of the wave also changes.

speed
the speed and wavelength increase but the frequency stays the same
the waves travel through water, but they do not carry the water with them. The ship moves up and down as the wave passes under it. The ship does not travel with the wave!
the sound wave will not make it to the ear drums. you wont hear the sound.
