The program explores the nature of mechanical waves, questioning how they move and what creates them. It demonstrates wave motion through various experiments, including using a slinky and a wave ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Originally intended as a way to stabilize sensitive instruments on ships during World War II, the Slinky is quite simply a helical spring with an unusually good sales pitch. But as millions of ...

sound waves cause air particles to vibrate back and forth; ripples cause water particles to vibrate up and down. A longitudinal wave is one in which the vibrations of the particles are parallel to ...

A longitudinal wave is one in which the vibrations of the particles are parallel to the direction in which the energy of the wave travels. compressions are regions of high pressure due to ...
