What is a wave? |
A disturbance that transfers energy from place to place |
|
|
What causes waves? |
Vibration \ Energy |
|
|
What is a medium? |
A material in which the wave travels (Solid, Liquid, Gas) |
|
|
Why does a wave need a medium to travel through? |
So it can transfer particles as it moves |
|
|
What is a mechanical wave? |
A wave that REQUIRES a medium to travel through |
|
|
What is a transverse wave? |
A wave that moves the medium at a direction perpendicular to the direction the wave travels |
|
|
What's a longitudinal wave? |
A wave that moves the medium parallel to the direction in which the wave travels |
|
|
What is a wavelength? |
A distance between two corresponding parts of a wave |
|
|
What is interference? |
When 2 waves interact with eachother |
|
|
What is the difference between destructive and constructive interference? |
Constructive: bigger amplitude Destructive: smaller amplitude |
|
|
What is diffraction? |
pending around a barrier and spreading out |
|
|
What is refraction? |
bending of waves due to a change of speed |
|
|
What is reflection? |
Hits a surface it can't pass through and bounces back |
|
|
What happens when a wave moves through an open barrier? |
It spreads out once it squeezes through the walls (Diffraction) |
|
|
What are seismic waves? |
Waves produced by earthquakes |
|
|
What is a tsunami and how is it formed? |
A tsunami is formed by earthquakes that form or occur underwater a tsunami is a large surface wave |
|
|
What happens when the pressure in rock builds up under the Earth? |
It breaks or shifts and releases energy in the form of seismic waves |
