Challenge Problems
Push your limits with challenges.
Question 1
If P-waves travel at 6 km/s and S-waves at 3.5 km/s, how much faster are P-waves compared to S-waves when both are traveling through the same layer?
💡 Hint: Subtract the speeds of both waves to find the difference.
Question 2
Imagine an earthquake occurs, and the distance from the epicenter is measured at 800 km. If P-waves arrive first followed by S-waves, how would scientists use the arrival time difference to determine Earth's structure?
💡 Hint: Consider why some places receive only P-waves and not S-waves.
