List of top Geophysics Questions on Seismic Waves asked in GATE GG

If \( \alpha \) and \( \beta \) are P- and S-wave velocities, respectively, then \( \alpha^2 - \frac{4}{3} \beta^2 \) is equal to: \[ (\kappa \text{ is the bulk modulus, } \mu \text{ is shear modulus, and } \rho \text{ is density}) \]

Which one of the following phases is a P-wave that converts to an S-wave during passage through the solid inner core?
