Use the diagram above (a stationary wave pattern showing displacement against distance, with a marked span of 21m) to answer this question. The diagram above represents a stationary wave. Determine the wavelength
- A. 6m
- B. 12mCorrect
- C. 17m
- D. 21m
Explanation
Based on the number of loops shown across the marked 21m span, the wavelength works out to 12m. (Note: this question depends on a value that was not fully legible in the source scan; the answer given is a best estimate.)
