The nomograms constructed are used to solve the following equations: I. Interceptā€time formula. 2. Critical distance formula. 3. Critical angle formula. 4. Critical angle and dip angle formula. 5. Vertical depth formula. %U https://www.earthdoc.org/content/journals/10.1111/j.1365-2478.1968.tb01964.x
