When a seismic wave crosses a boundary in what process will it change direction?
Refraction
A disturbance at the boundary between two media?
surface wave
Almost as soon as the depolarization wave begins a repolarization wave follows it across the membrane this occurs as?
This occurs as K+ diffuses out of the cell.
What is a boundary between two materials?
Surface Wave (APEX)
Why light bends towards normal when it enters from optically rare to optically denser medium why it does not bend away from the normal?
This is because of the speed of light getting reduced as it enters into the denser medium. Think of the FRONT of the wave as it enters a more-dense medium at an angle, and its speed decreases. Vizualize it in very slow motion: -- The wave-front arrives at angle, so part of it is across the boundary and into the new medium, while part of it is still out in the old medium. -- The part of the wave-front in the new medium is traveling slower, while the part that hasn't quite reached the boundary yet is still out in the old medium and traveling faster. -- If your vizualization is running accurately, this action is causing the whole wave-front to turn, becoming more parallel with the boundary, and its direction of motion turning toward the normal.
What happens when refraction occurs?
Refraction occurs when a wave bends as it crosses the boundary between different mediums (eg. air to glass). The wave bends because waves travel at different speeds in different mediums. When a wave enters a more dense medium (eg. air to glass), the wave slows down, and bends towards the 'normal'. When a wave enters a less dense medium (eg. glass to air), the wave speeds up, and bends away from the 'normal'. * The normal is an imaginary line which is perpendicular to where the light is entering the new medium.
When a wave bends as it passes from one medium to another what occurs?
Refraction is the change in direction of a wave when it reaches a boundary between two media due to traveling at different speeds in each medium.
The bending of a seismic wave as it crosses a boundary is called?

When a seismic wave crosses a boundary it will change directions in what process?

When a seismic wave crosses a boundary in what process will it change direction?
Refraction
How does a wave refract?
A wave undergos refraction when it crosses the boundary between two media in which it has different speeds.
A wave that occurs at the boundary between two media when transverse waves combine?
A standing wave occurs when two transverse waves combine.
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 a wave that occurs at or near the boundary of two different media?
Either Longitudinal, transverse, or a surface wave.
What is the difference between rarefaction and refraction?
Refraction occurs when a wave crosses a boundary from one medium to another. A wave entering a medium at an angle will change direction.Diffraction refers to the "bending of waves around an edge" of an object. Diffraction depends on the size of the object relative to the wavelength of the wave.bestfahadali@yahoo.com
