Refraction of this kind of wave results in two shadow zone Squeezes and pulls rocks in same direction as the wave travels Is refracted by Earth’s core Does not pass through Earth’s interior at all Does not pass through Earth’s liquid outer core 1. surface wave 2. P-wave 3. S-wave

2. P-wave

Explanation:

The p-waves pass through the mantel and the core and are slowed and are refracted by the mantle/core boundary forming at a depth of about 2900 km, the P wave are those that result of the two shadow zones that squeeze and pulls the rocks in the same direction as the waves travel and is refracted by the earth core.
