Question

When sesimic waves pass across the boundary between two different materials, ___________ .

• A. the waves change in velocity
• B. the waves refract
• C. the waves reflect
• D. all of the above

Answer 1

The correct option is D all of the above

Seismic wave is a wave of energy caused due to sudden break or explosion of a rock in the earth’s interior.

When seismic wave passes from one material to the other material it either reflects, refracts or changes it velocity.

This phenomenon of seismic reflection or refraction enables geologists to study the interior of earth because reflection and refraction differs with the type of material.
