plot the data in the photo for the 5 ves surveys and deduce the minimum number of layers that exist in the subsurface. why is this the minimum number?

Spacing (m) 32 Readings (ohms) Tai 39 34 0.32 0.12 15 0.26 0.11 7.2 4,35 0,7 2.8

Solution

The data can be plotted using Scatter plot. The following is the plot for the 5 ves surveys.

The minimum number is d.
