Which response best uses evidence or a diagram feature to support Define Wavelength Frequency Period Amplitude And Phase?.
- A.A. It points to the relevant observation, graph feature, field direction, or measurement and links it directly to define wavelength, frequency, period, amplitude and phase.
- B.B. It quotes a number or feature but does not say what it proves.
- C.C. It draws a conclusion from evidence that belongs to another subtopic.
- D.D. It ignores the evidence and gives only a memorised sentence.
Model answer
What a good answer should say
- Source Link answer 4203b0: A.
- It points to the relevant observation, graph feature, field direction, or measurement and links it directly to define wavelength, frequency, period, amplitude and phase.
- 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: Which response best uses evidence or a diagram feature to support Define Wavelength Frequency Period Amplitude And Phase? Route focus: waves / Progressive And Stationary Waves.
Key vocabulary for this item: wavelength, frequency, period, amplitude, phase. Option check: keep Source Link answer 4203b0: 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.
