It is simply called a change in speed.
Wave motion
Sound travels the same way through different mediums. Sound travels faster in denser mediums.
Sound travels through mediums in sound waves.
Light bends, when it light travels at different speeds in different mediums. Hope that helps.

Sound travels through mediums in sound waves.
it refracts because it travels in different velocities and other colors of light travel in different speeds When light crosses a boundary between mediums, it changes speeds, and it bends or changes the angle that it is travailing at when it crosses the boundary.
True
Light bends, when it light travels at different speeds in different mediums. Hope that helps.
The denser the medium, the faster sound travels in it.
Sound travels faster the more dense the medium
In general, sound will travel faster through a medium that's more dense, and slower through one that's less dense.
