Yes, WAVE motion is slowed by the higher Density of the Medium.
The character frequency would never change
Refraction.
Waves are said to have been refracted when they bend upon changing mediums. The waves have undergone refraction when moving from one medium to another.
When waves travel from one point to another energy is transferred through the medium. Waves are periodic vibrations or oscillations in a medium that propagate through the medium carrying energy in the form of the movement. Exceptions to this are light and gravity waves, which do not require a medium for propagation.
If your talking about wavelengths, like in light, it might change depending on the medium it moves trough...
Then, if they don't arrive from the direction perpendicular to the interface, they are refracted.

The frequency doesn't change as it is dependent only on the source.

it is called a DIFFRACTION
Waves only change direction when they intersect the other medium at an incident angle of other than 90o
Longitudinal waves
