Primary seismic waves are longitudinal waves. Longitudinal waves can travel through solids, liquids and gasses (although seismic waves are of to low a frequency to normally be heard). Secondary seismic waves are transverse waves and only travel through solids.
A machine or program to measure seismic waves that travel through the earth after an earthquake or explosion.
The time-distance graph of seismic waves shows the relationship between the time it takes for seismic waves to travel and the distance they travel. It helps in determining the speed at which seismic waves propagate through the Earth's interior and provides information about the structure and composition of the Earth's layers.

What does a seismograph use to record the drums vibrations
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
Seismic waves travel in all directins radiating out from the Earthquake's epicenter and/or focus.
seismic waves that travel through the earth
the ground
They get weaker as they travel out from the epicentre
(not seismic, seismic wave)Seismic waves are waves of energy that travel through the earth.
Secondary seismic waves travel slower than primary waves but they are much more destructive. Thus it carries more energy.
Primary seismic waves are longitudinal waves. Longitudinal waves can travel through solids, liquids and gasses (although seismic waves are of to low a frequency to normally be heard). Secondary seismic waves are transverse waves and only travel through solids.
A seismic travel time curve describes the relation between the travel time of a seismic wave and the epicentral distance. It is used to calculate the calculate the distance of the earthquake's epicenter from the seismograph.
