Question
- A. period: oscilloscope trace reasoning in a ray-box experiment at a glass boundary
- B. period: a generic statement that ignores normal lines, angles and direction changes
- C. period: a boundary mistake that confuses reflection versus refraction
- D. period: a different Unit 4.6 idea from outside Properties of waves
Answer
The correct answer is period: oscilloscope trace reasoning in a ray-box experiment at a glass boundary.
Explanation
period: 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 Properties of waves. It avoids the common boundary error of reflection versus refraction while keeping the learning objective visible.
Common mistake
