The Pressure wave is a longitudinal wave - it is a compression/rarefaction wave and has the highest velocity.
The Secondary wave is a transverse wave (side to side) and is much slower.

∙ 12y agoOn a seismograph, p-waves reach first.
P-waves are longitudinal waves, i.e. the energy travels through compression and expansion of the material medium, like sound waves. The movement of particles is in the direction of the wave propagation. They travel at roughly double the speed of S-waves (6-13 km/s in earth's crust)
S-waves are transverse waves; the movement of the particles is perpendicular to the direction of wave propagation. Speed: 3.5-7.5 km/s

A trick to remembering this:
P waves - Primary waves
S waves - Secondary waves

Which is faster to reach ground feather or ball in free fall?
In vacuum they reach ground exactly at the same time. In a medium other than vacuum the ball will reach ground first.
Longitudinal waves are called primary waves because they?
Reach recording stations first.
Would a crumple paper ball or rectangular shape paper reach the ground?
tHE BALL OF PAPER WOULD REACH THE GROUND FIRST. tHE RECTANGLE SHAPE WILL REACH LATER DUE TO THE AIR FOIL EFFECT(float down). iN A VACUUM THEY WOULD DROP THE SAME. Gravity is 9.8 m/s2.
When a canon ball and a marble roll down an inclined plane which one will reach the bottom first?
they will both reach at same time and speed. due to gravity measurement and many different answers. so due know though it isn't safe to test.
If a stone and a pencil are dropped simultaneously in vacuum fron the same height which of two will reach the ground first?
They will both hit the ground at the same time.
What waves are first to reach the seismograph?
p-waves
What waves are the first to reach a seismograph after an earthquake?
Primary waves
What types of waves are the first waves to reach seismograph stations?
P-waves are the first seismic waves to arrive at a seismograph station.
What type of waves reach a seismograph station first p of s?
P
Identify which type of seismic wave is described in each of the following a cannot tavel through the core B cause the most damage to buildings c are the first waves to reach seismograph stations?
S-waves cannot travel through the earth's outer core as it is liquid. Surface (Love and Rayleigh) waves cause the most damage to buildings. P-waves are the first to arrive at seismograph stations.
Which are faster s waves and p waves or surface waves?
The fast is primary wave which travels through liguid, solid and gas. This how Geologist know the outer core is liquid. Secondary waves travel through only solid. The primary wave are the first to reach the seismograph.
How does a seismograph records a earthquake?
when waves from an earthquake reach the instrament, the inertia of the weight keeps it stationary, while earth and the support vibrate. Seismographs amplify and electronically record ground motion.
After an earthquake which type of seismic waves reach seismometers last?
A surface wave is the last seismic wave to arrive after an earthquake.
What is the first mission on Halo Reach?
The first mission on Reach is Noble Actual. The first PLAYABLE mission is Winter Contingency.
What does mean to reach their goal?
a contest to reach a goal first
Who is the first person to reach southern point?
Roald Amundsen was the first person to reach the south pole.
Who was the first lady to reach the space?
who was the fist lady to reach the space
