Primary Waves from WaveText
Here, we make the characters move from side to side. Motion is parallel to the direction of wave propagation. These are like primary or compressional waves which move through the depths of the Earth when earthquakes occur.
Secondary Waves from WaveText
Here, we make the characters move up and down, with each character one-eighth of a phase behind the previous one. The motion is perpendicular to the direction of wave propagation. These are like secondary or shear waves which, like primary waves, propagate through the Earth after they are generated by earthquakes.
Ocean Waves from WaveText
Here, we make the characters move in circles with the with the upper component of the motion in the same direction as that of wave propagation. In this case, it is from left to right. These are like ocean waves that are generated by wind blowing across the water.
Rayleigh Waves
In this invocation of the WaveText applet, the characters rotate in circles, with the upper portion of the motion retrograde to the direction of the wave propagation. This is the way the Earth's surface moves in Rayleigh waves, which are surface waves created by earthquakes.
