Ask Echo about the UT L2 AI your AI study assistant
See what's on the UT L2 exam, test yourself with 5 quick questions, or find the plan that fits you.
You slide an angle beam probe away from a flaw. Which way does its echo move on the screen?
- You: Why does the echo move right when I slide the probe away from the flaw?
Echo
The screen shows time, and time is distance along the sound path. Slide back and the sound travels farther at that angle before it reaches the flaw, so the echo comes back later and sits farther right.
Key point
Longer sound path, later echo, farther right on the screen.
