How long does it take a p-wave to travel 5,000 km? How long does it take a p-wave to travel 5,000 km? 8 minutes 20 seconds Thursday, December 10, 2009 Page 73 Thursday, December 10, 2009 Page 74 How far does an S- wave travel in 16 minutes? How far does an S- wave travel in 16 minutes?
Q. What do you call the first wave that the seismograph recorded?
The P wave is designated the primary preliminary wave because it is the first to arrive at a seismic station after an earthquake. It travels at a speed usually less than 6 kilometers per second in the Earth’s crust and jumps to 13 kilometers per second through the core.

Q. What is the approximate P wave travel time from an earthquake if the P wave arrives at the seismic station 8 minutes before the S wave?
5 minutes
Q. When did the first P waves arrive at this seismic station?
The arrival time of the first earthquake P-wave at a seismograph station was (hours:minutes:seconds).
Q. How long does it take the P wave to travel 2000 km?
In a solid such as rock, the primary wave can travel at 5 km/sec; it would take 400 seconds, or about 6.7 minutes to travel 2,000 km. If traveling through water, the wave travels at about 1.45 km/sec and would need 1,379 seconds (23 minutes) to travel 2,000 km.
Q. What does S wave represent in ECG?
This is known as an S wave and represents depolarisation in the Purkinje fibres. The S wave travels in the opposite direction to the large R wave because, as can be seen on the earlier picture, the Purkinje fibres spread throughout the ventricles from top to bottom and then back up through the walls of the ventricles.
Q. What are leads V1 V2 V3 V4 V5 and V6 known as?
The precordial chest leads can be divided into groups which view specific areas of the heart. Leads V1, V2, V3, and V4 as a group effectively view the anterior portion of the heart and are called the anterior leads. Leads V5 and V6 collectively look at the lateral wall of the left ventricle.
