Medium |
Anything that has matter. Material a wave can pass through |
|
|
Waves carry____ from one place to another |
Energy |
|
|
What is a transverse wave? |
Where the medium moves at right angles to the direction of the wave |
|
|
What is a longitudinal wave? |
A wave which the vibration of the medium is parallel to the direction the wave travels |
|
|
Do all types of mechanical waves need a source of energy to produce it? |
Yes |
|
|
When a surfer rides an ocean wave on her surfboard she is actually riding on what part of the wave? |
Rest position |
|
|
What is a period |
Time required for one full cycle measured in seconds |
|
|
Amplitude is related to the amount of energy carried by a wave |
True |
|
|
In refraction when two parts of a wave travel through different mediums what happens to the speed of the two parts? |
They're different |
|
|
Two waves collide and become smaller what is it? |
Destructive Interference |
|
|
A sound wave is an example of what type of wave |
Longitudinal |
|
|
When an ambulance is close its loud when its far it is quite what is it? |
Doppler affect |
|
|
What is frequency |
The number of cycles that occur in one second |
|
|
Frequency increases wavelength... |
Decreases |
|
|
Formula of speed of a wave |
Frequency * wavelength or speed divided by wavelength |
|
|
For refraction to occur in a wave the wave must do what? |
Enter a new medium at an angle |
|
|
If two waves collide and the wave is smaller the inference is |
Destructive |
|
|
Node |
A point in a standing wave that has no displacement |
|
|
Surface wave |
A wave that travels a surface separating two media |
|
|
Where do surface waves travel? |
Between a medium |
|
|
Reflection |
Occurs when a wave bounced off a surface it cannot pass |
|
|
Destructive |
Occurs when two or more waves combine to produce a wave with smaller displacements |
|
|
Constructive |
Occurs when two or more waves combine to produce a wave with larger displacements |
|
|
Diffraction |
Bending of a wave as ot moves around an obstacle or passes through a narrow opening |
|
|
Refraction |
Bending of a wave as it enters a new medium at an angle |
