when calculating the reflection R with the K formule. somethimes you have a negative reflection value. what is the impact of this negative reflection value and how is this vissible on the screen?
The negative value means the polarity of the wavelet is flipped. So, if the incident wave is Black-white-black, the reflected wave will be White-black-white.
I'm seeing different K values online. For clay you have 40 and I'm seeing online numbers like 10 and 20. Is there a good resource for common K values we might encounter in the field?
Clay usually has a high water content so the K values tend to be 40+. A clay with a K of 10-20 would have to be very dry. Here is the table that we use in our training courses: Material K Air 1 Gasoline 2 Ice 3 Dry Sand 5 Granite 6 Dry Salt 6 Limestone 8 Shale 15 Saturated Sand 25 Silts 30 Clays 40 Fresh Water 80 Sea Water 80 Metal ∞

Great Thanks
