They bend at the interface between two media.
The direction of light propagation can be changed at the boundary of two media having different densities. This property is called refraction, and is illustrated in the following figure for the boundary between air and water.
Rayleigh Waves propagate along boundary between two dissimilar solid media, in a plane perpendicular to the surface and containing the direction of propagation.

The direction of the wave changes if its speed is different in the two media.

Reflection occurs when seismic wave bounces backward as it reaches a boundary. It refers to the change in direction of a wave front at an interface between two different media.
