Back to our radio signal. The electrons in our wire are moving, but not in one direction. These electrons are moving back and forth. Actually, the wave displayed in the activity is a representation of ...

These electrons are moving back and forth. Actually, the wave displayed in the activity is a representation of the back and forth movement of electrons. If the wave has a frequency of 200,000 Hz ...

Explain that earthquake waves move particles of material in different ways: whereas, compressional waves create a back and forth motion parallel to the direction of the waves, shear waves create a ...

whether they're called waves or rays, are generated by particles in motion. In a radio signal, for example, negatively charged electrons quickly move back and forth in an antenna. This movement ...

Adrian Shine, an expert on Loch Ness, has recorded the waves moving slowly underwater using ... it "piles up" and pushes colder water down and back towards Fort Augustus at the other end of ...
