|---|---|---|---|---|---|
| definition Medium (vocab) | material solid, liquid or gas through which a wave can travel
🗑
|
||||
| definition Transverse Wave (vocab) | a wave in which the particles of the medium move perpendicular to the direction the wave is traveling
🗑
|
||||
| definition Crest (vocab) | the highest point in the wave
🗑
|
||||
| definition Trough (vocab) | the lowest point in the wave
🗑
|
||||
| definition Longitudinal Wave (vocab) | a wave in which the particles of a medium vibrate parallel to the direction of a wave motion
🗑
|
||||
| definition Compression (vocab) | where by particles are pushed together
🗑
|
||||
| definition Rarefaction (vocab) | where by particles are spread apart
🗑
|
||||
| definition Mechanical Waves (vocab) | waves that require a medium can travel through more than one medium
🗑
|
||||
| definition Electromagnetic Waves (vocab) | waves that travel without a medium
🗑
|
||||
| definition Amplitude (vocab) | as waves pass through particles in the medium vibrate up, down and back-n-forth
🗑
|
||||
| definition Wavelength (vocab) | the amplitude of a wave describes the amount of the up, down and side-to-side displacement
🗑
|
||||
| definition Frequency (vocab) | the number of waves that pass a point in a given amount of time
🗑
|
||||
| definition Hertz (vocab) | One wave length per second
🗑
|
||||
| definition Wave Speed (vocab) | The speed at which waves travel
🗑
|
||||
| definition Force (vocab) | energy used to move an object a certain distance, measured in Newtons
🗑
|
||||
| definition Work (vocab) | push or pull of an object in order to change the motion
🗑
|
||||
| definition Power (vocab) | the rate at which work is done, measured in watts
🗑
|
||||
| what is the difference between compression and rarefaction? | compression is where particles are pushed together while rarefaction is when particles are spread apart.
🗑
|
||||
| what is the difference between Wave speed and Hertz? | Hertz is one wave length per second while wave speed is the speed at which waves travel.
🗑
|
||||
| what is the difference work and power? | work is a push or pull of an object in order to change the motion while power is the rate at which work is done, measured in watts.
🗑
|
||||
| what is the difference between a crest and trough? | Crest is the highest point in the wave while the trough is the lowest point in the wave.
🗑
|
||||
| what is the difference between electromagnetic waves and force? | electromagnetic waves travel without an medium with force uses energy used to move an object a certain distance, measured in Newtons
🗑
