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