Question
- A. wave speed: ripple tank practical evidence in an oscilloscope trace from a signal generator
- B. wave speed: a generic statement that ignores cycle spacing, period marks and frequency readings
- C. wave speed: a boundary mistake that confuses frequency versus period
- D. wave speed: a different Unit 4.6 idea from outside Properties of waves
Answer
The correct answer is wave speed: ripple tank practical evidence in an oscilloscope trace from a signal generator.
Explanation
wave speed: ripple tank practical evidence in an oscilloscope trace from a signal generator is correct because it uses the named evidence from an oscilloscope trace from a signal generator and stays anchored to Properties of waves. It avoids the common boundary error of frequency versus period while keeping the learning objective visible.
