Surface Waves
surface waves
These waves are called boundary waves or interface waves. They are formed due to the interaction of two different media and can exhibit characteristics of both types of waves present at the boundary.
The type of waves that are combination waves occurring at the boundary between two media are known as interface waves or surface waves. These waves travel along the surface of the medium and are influenced by the properties of both media they are interacting with.
Usually part of the wave energy is reflected, and part of the wave energy passes through, possibly at a different angle (i.e., refraction may occur).
For a light ray to refract when it strikes the boundary of a different medium, two things must occur: the light ray must enter the new medium at an angle, and the speed of light must change as it transitions from one medium to another, causing the light ray to bend.
When two media have the same index of refraction, it means that light travels at the same speed through both media, so there is no change in speed or direction of the light at the boundary between them. This results in no refraction occurring as there is no bending of the light rays.
Earthquakes can occur at a transform boundary.
Eyjafjallajokull volcano is located on the divergent boundary between the North American Plate and the Eurasian Plate in Iceland.
