Square waves form when two wave systems collide, creating dangerous ocean patterns that threaten boats and swimmers.

Seismic readings of the interior of Mars strongly suggest large quantities of water buried 6 to 12 miles underground.

Traveling through the interior of the Earth, body waves arrive before the surface waves emitted by an earthquake. These waves are higher frequency than surface waves. P waves are also known as ...

This property of waves is called refraction and commonly occurs with light rays. A normal is a dotted line drawn perpendicular to the surface of the refracting material, at the point of entry of ...
