Question
- A. ultrasound reflection: oscilloscope trace reasoning in a ray-box experiment at a glass boundary
- B. ultrasound reflection: a generic statement that ignores normal lines, angles and direction changes
- C. ultrasound reflection: a boundary mistake that confuses reflection versus refraction
- D. ultrasound reflection: a different Unit 4.6 idea from outside Waves for detection and exploration (physics only)
Answer
The correct answer is ultrasound reflection: oscilloscope trace reasoning in a ray-box experiment at a glass boundary.
Explanation
ultrasound reflection: oscilloscope trace reasoning in a ray-box experiment at a glass boundary is correct because it uses the named evidence from a ray-box experiment at a glass boundary and stays anchored to Waves for detection and exploration (physics only). It avoids the common boundary error of reflection versus refraction while keeping the learning objective visible.
