Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the related scientific discipline?Seismology, which applies similar principles to study Earth's interior using seismic waves
2. How do scientists use waves to look inside a bridge?They send special waves from a source, then listen with many receivers. By measuring how long the waves take to travel, they build a picture of the bridge’s inside.
3. Why is stress wave tomography useful for safety?It can find cracks or hidden problems in structures without damaging them. This helps engineers fix issues before they become dangerous.

Wave Inversion: A mathematical process to determine the physical properties of a medium from measured wave propagation data.
Non-Destructive Evaluation (NDE): Techniques used to assess the properties or integrity of a material or system without causing damage.
Full Waveform Inversion (FWI): An advanced tomographic method that uses the entire recorded seismic waveform to update a subsurface model.
