Waves in strata |

The first task in interpretation of seismic data
is to figure out the approximate numerical value
of the **vertical exaggeration**.
The vertical exaggeration is because it is the ratio of
the apparent slope
to the actual slope
where
.
Since
the velocity generally
*increases* with depth,
the **vertical exaggeration** generally
*decreases* with depth.

For velocity-stratified media,
the time-to-depth conversion formula is
