How do waves behave when they hit a boundary?

∙ 9y agoThere are several possible things that may happen when waves strike a surface or boundary. This may cause deflection, reflection and also a warp-surround aspect. This is as a result of the angle of the waves and the nature of the surface.

∙ 14y agoIf you mean: "What happens to sound when it hits a barrier?"
That all depends on the type of barrier.
A flat, solid and hard barrier will most likely bounce the sound waves off it in a direction that depends on how the waves meet the barrier. (think of a "sound-mirror")
However, if you were to have a something porous/soft,etc. like fabric or foam, the waves will be (partially) absorbed.
In general, both will happen. The degree to how much of the original waves energy is transformed into a reflected wave and how much into a decayed abosrobed wave will depend on the medium.

The sound either reflects or gets absorbed.

What is the scientific explanation for echos?
An echo is a sound wave that has reflected off a boundary
Why doesn't a feather make sound when it hits the ground?
its too light
What happens when light hits a rough surface?
when light hits a rough surface it scattters.
What is a boundary where 2 plates move apart?
It is called a divergent plate boundary.
When a sound wave moves past a point in air what happens to the density of air at this point?
The density of air increases and then decreases as the sound wave passes.
What happens when sound hits a thin membrane?
What happens when sound hits a thin membrane is that it vibrates the tympanic membrane. The tympanic membrane is also known as the eardrum.
What happens when sound hits soft materials?
generally speaking, the sound is absorbed.
What happens when sound hits a surface?
It bounces back.
When does light cross a boundary but not refract?
This happens if the light makes a 90 degree angle with the boundary (hits is straight on), so it just keeps going in a straight line.
What happens when a sound wave hits a small thin membrane?
The membrane (such as you eardrum) vibrates.
What happens if thunder hits earth?
Thunder is sound waves. They hit Earth all the time, and nothing in particular happens.
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
What happens at a ocean ocean boundary?
At an ocean ocean convergent boundary, there will be a formation of volcanoes.
What happens when you cross the boundary in cricket?
we will get 4runs
What happens at a ocean ocean convergent boundary?
At an ocean ocean convergent boundary, there will be a formation of volcanoes.
What happens when sound hits an object?
They are either absorbed [softsurface, e.g. wool] or refected [hard surface, e.g. metal]
Does sound go quieter when it hits a material?
When sound reaches a boundary between two different media, some energy is reflected back, some is absorbed as heat, and some is transferred through the new medium. The overall effect of this is that the sound is indeed quieter in the new medium than it was in the old.
