Is every 13th wave bigger?
It is not true that every 13th wave is larger than the others, as claimed in the film. In fact, there exists no pattern in wave sizes. In the original Kon-Tiki documentary, it was shown that the crew simply waited for a wave big enough to carry them over the reef.
Where do P waves travel?
P waves can travel through solids, liquids and gases. That’s one big difference between them and the other types of seismic waves, which typically travel only through solids (such as rock).
How is epicentral distance calculated?
Measure the distance between the first P wave and the first S wave. In this case, the first P and S waves are 24 seconds apart. Find the point for 24 seconds on the left side of the chart below and mark that point. According to the chart, this earthquake’s epicenter was 215 kilometers away.
How long does it take as wave to travel 8000 km?
Approximately 11 minutes and 20 seconds
How long does it take AP wave to travel 300 km?
approximately 70 seconds
How do you calculate lag time?
Time = Distance / Speed So, the lag time difference between the two vehicles (10 hours – 5 hours) is 5 hours. What would the lag time be if the distance traveled were 500 miles? Vehicle A would take 10 hours to travel 500 miles, but Vehicle B would take 20 hours. The lag time here is 10 hours.
How long does it take AP wave to travel 3900 km?
WAVE TRAVEL TIME AND DISTANCE TRAVELED
| P-WAVES | S-WAVES | |
|---|---|---|
| Distance (km) | Time (min.) | Distance (km) |
| 8900 | 12:00 | 3900 |
| 10000 | 13:00 | 4200 |
| 14:00 | 4700 | |
Which wave does not travel through liquids?
S-waves
How fast do different types of seismic waves travel which is the fastest the slowest?
There are two types of body waves: P-waves travel fastest and through solids, liquids, and gases; S-waves only travel through solids. Surface waves are the slowest, but they do the most damage in an earthquake.
What happens to the time difference between primary and secondary waves as the distance gets longer?
What happens to the times difference between primary and secondary waves as the distance traveled gets longer? The time differences become bigger. Suppose a primary and secondary wave both travel a distance of 4,000 km before they are picked up by a seismograph.
What is the difference in arrival time of P wave and S wave?
The different waves each travel at different speeds and therefore arrive at a seismic station at different times. P waves travel the fastest, so they arrive first. S waves, which travel at about half the speed of P waves, arrive later.
What is the difference of P wave and S wave?
P waves travel at speeds between 1 and 14 km per second, while S waves travel significantly slower, between 1 and 8 km per second. The S waves are the second wave to reach a seismic station measuring a disturbance. The difference in arrival times helps geologists determine the location of the earthquake.
