Question
(II) What is the ratio of $(a)$ the intensities, and $(b)$ the amplitudes, of an earthquake $P$ wave passing through the Earth and detected at two points 10 $\mathrm{km}$ and 20 $\mathrm{km}$ from the source.
Step 1
This can be represented by the equation $I_1/I_2 = (r_2/r_1)^2$, where $I_1$ and $I_2$ are the intensities at distances $r_1$ and $r_2$ respectively. Show more…
