What happens when a wave bounces back after it hits a boundary?
that depends on the boundary if it is a fixed or hard boundary, there is zero displacement and the reflected wave changes its polarity , i.e. it undergoes 180 deg phase change if it is a flexible or soft boundary, the restoring force is zero and the reflected wave has the same polarity in other words there is no change in phase
When a wave reflects from a fixed boundary the only change in the wave is the direction of travel?
true
The bending of a seismic wave as it crosses a boundary is called?
refractionRefraction
What is a wave that occurs at or near the boundary of two different media?
Either Longitudinal, transverse, or a surface wave.
Reflection from a hard boundary produces what?
a 180 degree phase shift of the incident wave in the reflected wave.

What is a wave that occurs at the boundary between two media when transverse and longitudinal waves combine?
megnetic wave and or a surface wave
What is it called when a selsmic wave bounces backward when it reaches a boundary?
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.
What is it called when a light ray passes through an optical lens?
We have learned that refraction occurs as light passes across the boundary between two media. Refraction is merely one of several possible boundary behaviors by which a light wave could behave when it encounters a new medium or an obstacle in its path. The transmission of light across a boundary between two media is accompanied by a change in both the speed and wavelength of the wave. The light wave not only changes directions at the boundary, it also speeds up or slows down and transforms into a wave with a larger or a shorter wavelength. The only time that a wave can be transmitted across a boundary, change its speed, and still not refract is when the light wave approaches the boundary in a direction that is perpendicular to it. As long as the light wave changes speed and approaches the boundary at an angle, refraction is observed.
When a seismic wave boundary it will change directions in the process of?
refraction
A disturbance at the boundary between two media?
surface wave
The bending of a seismic wave as it crosses a boundary is called?
refractionRefraction
How does a wave refract?
A wave undergos refraction when it crosses the boundary between two media in which it has different speeds.
Which property of a wave changes as the wave travels across the boundary between two different media?
it is speed
What is a wave that occurs at or near the boundary of two different media?
Either Longitudinal, transverse, or a surface wave.
