It should normally not change.
It refracts some and reflects some.
Their speeds are exactly identical.
It depends whether the new medium is "heavier" or "lighter" than the previous medium. If it is "heavier" then the wave slows down. If it is "lighter" the wave speeds up.

When the wave hits an object it reflects (bounces) off the object

With the same speed -Apex (1.2.4)

it doesnt reflect but it stays on the object and only reflects enough so that the human eye can see it.
The light wave could be absorbed by the object, in which case its energy is converted to heat. The light wave could be reflected by the object. And the light wave could be transmitted by the object. ...
A P wave reflects atrial depolarization.

That's the incident wave.
Nothing happens if you wave at them.
