|
The y-axis
Where do you find the dependent variable on a graph
|
There will always be two poles
What happens if you cut a magnet in half
|
it should have branches
Draw a parallel circuit
|
Must have a complete crest and complete trough
Draw a one complete wave. No more and no less
|
Longitudinal
What type of wave is a sound wave
|
|
Sonar
This is used to send sound wave into an area to find out what is looks like
|
The lines should connect at the poles
Draw a picture of the field lines of two magnets that attract

Infrasound
This is a sound that is at a lower frequency than humans can hear
|
Solar Radiation
What can Earth's magnetic field protect us from?
|
