The change in the physical properties of earths interior at the mantle core boundary makes p waves as they pass through the boundary

Bend

P wave is a longitudinal earthquake wave that travels through the interior of the earth and is usually the first wave to be recorded by a seismograph. This is actually a wave that shakes the ground back and forth in the same direction and the opposite direction as the direction the wave is moving. But the change in any physical properties of earths interior at the mantle core boundary makes p waves bend through its boundaries.
