When a wave reflects from a fixed boundary the only change in the wave is the direction of travel?
true
When a wave approaches a boundary between two media obliquely does its direction of motion change or remains the same?
The direction of the wave changes if its speed is different in the two media.
What is angular value of normal in refractive index?
The "normal" to a surface or a boundary is the direction perpendicular to it. Within the scope of this discussion, it has nothing to do with refractive index.
What is it called when light blends as it moves from one substance to another?
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.
What is refraction and defraction?
Refraction is the direction of light propagation that can be changed at the boundary of two media having different densities. Defraction refers to the "bending" of light.
What is guided media?
Transmission media with a physical boundary..
Light which bounces off the surface of an object is called?
When light changes direction as it passes through a boundary.
Why is there a boundary that separates Canada and the US?
It's there to show that your crossing into a different country's territory.
What does crossing the Rubicon mean in today's society?
Crossing the Rubicon: the pass of a boundary, a limit, a river, a point from which the return is impossible. Or, today, to make an irreversible decision.
When a seismic wave crosses a boundary in what process will it change direction?
Refraction
Which of the three main boundary types is least common?
In geology, the least common type of boundary is transform boundary. Its relative motion is predominantly horizontal in either sinistral or dextral direction.
What are the 2 conditions when the direction does not change on refraction?
-- 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.
What happens to light when it strikes the boundary of the two media an angle equal to the critical angle?
It gets refracted so that its direction of propagation is the boundary line.
When a wave reflects from a fixed boundary is the only change in the wave is the direction of travel?
true
When a wave reflects from a fixed boundary the only change in the wave is the direction of travel?
true
When moving away from a divergent boundary in either direction what happens?
The rocks increase in age
What is transformed fault boundary?
A transform boundary, or conservative plate boundary, is a type of fault at the margin of two adjacent tectonic plates were the relative motion is horizontal in either sinistral or dextral direction between the two.
