The light waves bounce off the surface and travel in a new direction
The molecule of the medium vibrates at the dirction in which the wave travels
Sound waves travel through any medium with the exception of vacuum. The denser the medium, the faster the sound waves travel, because the waves can be farther apart..
Because they are waves, and waves travel that way.
Rock under stress breaks at the focus, releasing energy and vibrations called seismic waves, which travel away from the focus, through Earth's interior, and across the surface. The three types of seismic waves are: Primary waves: The first to arrive at seismographs Secondary waves: The second to arrive at seismographs Surface waves: The last and most severe to arrive at seismographs
p waves
They get weaker as they travel out from the epicentre
The waves will be bent or reflected.
Seismic waves travel in all directins radiating out from the Earthquake's epicenter and/or focus.
The waves become smaller.
Seismic p
Seismic waves are the earths crust vibrating. there are two types of waves P-waves and S-waves (Primary and Secondary) Primary waves travel faster than s waves and can travel through solid and liquid, S-waves can only travel through solids
The light waves bounce off the surface and travel in a new direction
S waves shear rock back and forth as they travel through it.
They start to get smaller
all directionits in the first sentence of the book
It's the focus
