What will show the highest amplitudes?

What will show the highest amplitudes?

B) surface waves is the answer.

Which wave type has the largest amplitude?

Gamma rays
Gamma rays has the greatest amplitude among all electromagnetic waves.

What does wave amplitude on a seismograph show?

Amplitude—the maximum disturbance or distance from the constant point. On a seismogram the horizontal time line is flat until there is a ground disturbance which is recorded as wave, or seismogram. The amplitude of a seismic wave is the amount the ground moves up or down.

Which wave will have the strongest reading on a seismograph?

Surface waves usually have the strongest vibrations and probably cause most of the damage done by earthquakes. Body waves are of two types, compressional and shear.

Which type of wave moves the fastest and this will reach the seismograph first?

P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation. In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.

Which type of wave moves the fastest and thus will reach the seismograph first quizlet?

Which of the three types of seismic waves travels through rock with the greatest velocity? – As elastic energy is released in an earthquake, P waves are the first seismic waves to arrive at a seismograph.

What is a high amplitude wave?

A high amplitude wave is a high-energy wave, and a low-amplitude wave is a low-energy wave. In the case of sound waves, a high amplitude sound will be loud, and a low amplitude sound will be quiet. Or with light waves, a high amplitude beam of light will be bright, and a low amplitude beam of light will be dim.

How do you find the amplitude of a seismograph?

The amplitude is the height (on paper) of the strongest wave. On this seismogram, the amplitude is 23 millimeters. Find 23 millimeters on the right side of the chart and mark that point. Place a ruler (or straight edge) on the chart between the points you marked for the distance to the epicenter and the amplitude.

What are the largest waves on a seismogram?

Surface waves travel a little slower than S waves (which, in turn, are slower than P waves) so they tend to arrive at the seismograph just after the S waves. For shallow earthquakes (earthquakes with a focus near the surface of the Earth), the surface waves may be the largest waves recorded by the seismograph.

What kind of waves do you see on a seismogram?

Typically, one can recognize the arrival of different wave types: P (the fastest traveling waves), S (shear waves), and surface waves. On these seismograms you may see local earthquakes in Northern California and earthquakes elsewhere in the world. Not all the wiggles seen on the seismograms are due to earthquakes.

How is the magnitude of an earthquake determined on a seismogram?

Magnitude is then derived from the amplitude of the waves on the seismogram and the distance of the earthquake from the seismograph. When P and S waves strike the surface of the earth they initiate a third kind of wave, called surface waves, which travel over the earth’s surface. These are the slowest waves.

How are seismic waves different from sound waves?

The “disturbance” can be an alternating electromagnetic field strength (light), a variation in water height (ocean waves), a variation in material density (sound waves), or a distortion of the shape of the ground (seismic waves). If you’ve felt Earth shake during an earthquake or explosion then you’ve felt seismic waves.

What kind of drum recorder makes seismograms?

Pictured here are Helicorders®, a common type of drum recorder, manufactured by Geotech Instruments, LLC. The seismograms displayed are from a few of the seismograph stations routinely recorded by the Northern California Seismograph Network.
