The discussion revolves around a problem related to mechanical waves, specifically seismic waves recorded after an earthquake. The original poster presents a scenario involving the time difference between the arrival of transverse and longitudinal waves at a seismic station, along with their respective speeds.
The discussion is ongoing, with participants offering guidance on the importance of demonstrating prior thought on the problem. There is a focus on steering the conversation through questions rather than providing answers, indicating a productive direction in the dialogue.
Participants note the importance of adhering to forum guidelines, which require that students show their thought process when seeking help. This reflects a constraint on the type of assistance that can be provided in the discussion.
Let, V transverse be v1 and V longitudinal be v2.Harli said:Homework Statement:: A seismic station records the transverse wave 10s after recording the longitudinal wave. Find the distance of the seismic station from the center of the earthquake.
V transverse=300m/s
V longitudinal=500m/s
Relevant Equations:: f=1/T or f=N/t
λ = v/f

Hi @raawe. Welcome to PF. You have made the same mistake that I did when I arrived here!raawe said:Let, V transverse be v1 and V longitudinal be v2.
If 'd' is the distance of the seismic station from the center of the earthquake, we have -
d/v1 - d/v2 = 10...solve for d!
My apologies. I will take from now.Steve4Physics said:Hi @raawe. Welcome to PF. You have made the same mistake that I did when I arrived here!
If anyone asks for help with homework, they need to show that they have already thought about about the problem. See point 4 in the guidelines: https://www.physicsforums.com/threads/homework-help-guidelines-for-students-and-helpers.686781/
So we typically 'steer' people, rather than directly solve their problem. Often that involves a series of questions and answers. That's why @Doc Al replied as in Post #2.
