A disturbance at the boundary between two media?

"boundary"

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

In general, its speed changes. Also, its direction changes if it isn't initially perpendicular to the boundary. ...

A wave undergos refraction when it crosses the boundary between two media in which it has different speeds. ...

-- Light approaches the boundary between any two media along the normal direction. -- Light approaches the boundary at any angle and the indexes of refraction of both media are equal. ...

A standing wave occurs when two transverse waves combine.

megnetic wave and or a surface wave

One boundary between the two is ?

The boundary between two materials can be many things. This boundary can be a border or a divider for example. ...

The density. Refraction occurs at the boundary between two media of differing densities, such as air and water. ...

Boundary or interface.

The boundary region between two ecosystems is called an ecotone.

The boundary is known as a border between two states or countries.

It's the line (boundary) between two countries.

When a wave meets a boundary between two different materials, part of the wave is reflected. The reflected wave travels back through the material to the detector. The time it takes to reach the detector can be used to calculate how far away the boundary is. The results may be processed by a computer to give an image. ...

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. ...

Mission Lake is the boundary between the two northern states.

The boundary that forms between two different air masses is called a front ...

Between these two continents there is a divergent boundary.

That happens right at the "interface" or "boundary" ... the exact place where the two media meet, and it's a different one on each side of that point. ...

An ethnographic boundary is the dividing line between two ethnic groups. This can be a physical or a theoretical boundary. ...

Collision between two plates produces a convergent plate boundary.

Often times a street is the boundary between two rival gangs.
