Exam-style question
Try this first
A student makes a mistake while revising Define Wavelength Frequency Period Amplitude And Phase. Which correction is most accurate?.
- A.A. The correction is to keep define wavelength, frequency, period, amplitude and phase separate from the common neighbouring idea in Progressive and stationary waves, then explain the tested distinction.
- B.B. The mistake is harmless because the two ideas always mean the same thing.
- C.C. The correction is to memorise the wording without explaining the distinction.
- D.D. The answer should move to a different Progressive and stationary waves topic instead of fixing the misconception.
Model answer
What a good answer should say
- Source Link answer c0d503: A.
- The correction is to keep define wavelength, frequency, period, amplitude and phase separate from the common neighbouring idea in Progressive and stationary waves, then explain the tested distinction.
- is correct because it matches Define wavelength, frequency, period, amplitude and phase.
- through phase difference, path difference, stationary wave, progressive wave.
Explanation
Why this works
Stem being answered: A student makes a mistake while revising Define Wavelength Frequency Period Amplitude And Phase. Which correction is most accurate?
Route focus: waves / Progressive And Stationary Waves. Key vocabulary for this item: wavelength, frequency, period, amplitude, phase.
Option check: keep Source Link answer c0d503: A because it matches the stem; reject alternatives that change wavelength, frequency, period or use a neighbouring model. The explanation should keep the answer tied to these exact words rather than a general physics summary, using units, graph evidence or equation reasoning only when they are relevant to the stem.
