What happens when a wave passes a barrier or moves through a hole in a barrier?

it bends and spreads out


What is it called when a wave bends around an obstacle?

When a wave bends around an obstacle, it is called diffraction.


Diffraction occurs when waves around the edge of a barrier?

Diffraction is phenomena that occurs when a wave encounters an obstacle. This happens when a wave reaches an obstacle that is comparable in size to it.


What wave bends around a barrier?

with diffraction


What is it called when a wave curves or bends around a barrier?

I believe you are referring to Refraction.


When a light wave bends around a barrier or the edge of an opening the resulting waves can?

interfere with each other


When a wave bends around a obstacle what is it called?

When a wave bends around an obstacle, it is called diffraction.


When a wave moves through an opening in a barrier its?

Bends and spreads out.When waves of any kind, sound, light electromagnetic radiation hit a gap in a barrier that is on the same scale as the wavelength then diffraction will occur. Diffraction is the bending of the wave and this appears as circular waves when we observe this effect with water.A common diffraction grating can be seen on a CD or DVD. The light spreads and we see this as different colours.


When a sound wave bends around a barrier so you can still hear the sound even though you cant see the source the wave has undergone what?

The sound wave has undergone refraction.

Does a wave travels trough a hole in a barrier it bends?

If the wave travels through a slit or hole that is is small with respect to the wavelength, then the wave can bend quite a bit.


What are 3 ways that waves change direction?

Three ways that waves change direction are reflection, refraction, and diffraction.
