Consider two different 3-dimensional waves traveling through a section of the earth (e.g. froman earthquake). If the first wave has 5.0 times the energy of the second, what is the ratio ofamplitudes of the two waves?
Homework Answers
As we know that -
Power (P) = Energy per second (E)
And the power is proportional to intensity.
Also, intensity is proportional to square of amplitude
This means -
Energy (E) is proportional to square of amplitude
So -
E1 / E2 = (A1 / A2)^2
=> A1 / A2 = sqrt(5) = 2.236
So, the ratio of amplitudes of the two waves = 2.236 (Answer)

When an earthquake occurs, two types of sound waves are generated and travel through the earth....
When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 117 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of...

Question 6 (3 points) An earthquake emits both S-waves and P-waves which travel at different speeds through the earth. An S-wave travels at 5000 m/s and a P-wave travels at 9000 m/s.

Suppose that p- and s-waves traveled in straight lines through the Earth (in fact, they don't, but we will make this approximation for this problem). Also suppose that the angular distance from the epicenter (location of the earthquake) on the Earth's spherical surface to the location on the surface beyond which no s-waves can be observed from an earthquake (the angle between the earthquake epicenter and the s shadow zone) is 120 degrees (i.e., the two points are located 1/3...

3. Earthquake warning system A typical earthquake produces two types of seismic waves. P ("primary" seismic waves are longitudinal waves that move through the earth's upper crust with speed anywhere from 3 km/s to 5 km/s (the exact speed depends on the local composition of the earth's crust). S ("secondary") waves are transverse waves that move slower than P waves. The S-wave speed is typically about 60% less than the P-wave speed in any given material. The map below shows...
