Question

question 1 of 10
the bending of a seismic wave as it crosses a boundary is called
a. rarefaction
b. reflection
c. refraction
d. absorption

Explanation:

• Rarefaction: Refers to a region in a wave where the particles are spread apart, not related to bending at a boundary.
• Reflection: Occurs when a wave bounces back from a boundary, not bending through it.
• Refraction: Is the bending of a wave as it crosses a boundary between two different media (which is what seismic waves do when crossing boundaries in the Earth).
• Absorption: Is when a wave's energy is taken in by a medium, not bending.

Answer:

C. refraction
