At a depth of approximately 2,500 km within the Earth, P-waves (primary waves) continue to travel but undergo changes in velocity and behavior due to the increasing pressure and temperature conditions. As they move through the Earth's mantle and into the outer core, P-waves can experience refraction and may slow down as they transition from solid to liquid regions. However, P-waves are capable of traveling through both solid and liquid, so they remain detectable even at these depths. The core-mantle boundary, located around 2,900 km deep, marks a significant change where P-waves are refracted due to the transition from the solid mantle to the liquid outer core.
