What do you call the change in direction of a wave at a boundary?
S3eed751
The terminology is the same for all waves, including light - so reflection or refraction depending on what you mean by change of direction. Firstly thanks for answering, I meant if you had water waves travelling from deeper to shallower water. The wavefront change direction when entering the shallower. so http://wiki.answers.com/Q/What_do_you_call_the_change_in_direction_of_a_wave_at_a_boundary" The effect is the same as bending of light as it goes from air into glass, for instance, it is refraction.

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.
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.
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
How does a change in speed cause a wave to change direction?
newton's

true

true
When a seismic wave crosses a boundary in what process will it change direction?
Refraction

The direction of the wave changes if its speed is different in the two media.
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.
Why the light wave entering the second medium show no change in direction?
I can't see the setup of your experiment, so there's no way I could know why that happened in your case. But I can think of two possibilities where that would happen: 1). The light wave would not change direction if the refractive index of both media is the same number, regardless of what direction it approaches the boundary from. 2). The light wave would not change direction if it approaches perpendicular to the boundary, regardless of the refractive index of either medium.

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.
When a seismic wave boundary it will change directions in the process of?
refraction
What happens to the direction of the wave as it passes into the air?
The direction of the wave will eventually change to where the wind is blowing.
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.
