Consider an imaginary earth model of thick fluid core surrounded by a thick mantle and thin or no crist. The density in the mantle increases from 3.0 gm/cc at the surface to 5.0 gm/cc at the core -mantle boundary, and it abruptly increases to 10.0 gm/cc in the care. The velocity of the P wave, increase from 3.0 km/sec to 8.0 km/sec in the mantle, and is abruptly falls to 4.0 km/sec in the core. Direct P waves omanating from an earthquake at angles of incidence less than sin-3(3/16) cannot be received anywhere on the earth's surface. Further the time of arrival of the P wave increases at a rate of 250 sec/radian prior to the onset of shadow zone,
The radius of earth model is,
