In the simplified sine-wave picture of a water wave, what are the uppermost and lowest positions of the wave called, respectively?
ANode and antinode
BAmplitude and wavelength
CCrest and trough
DFrequency and period
Answer & Solution
Correct answer: C. Crest and trough
1. The uppermost position of the wave is called the crest.
2. The lowest position of the wave is called the trough.
3. Node, antinode, amplitude, wavelength, frequency, and period are all separate wave properties, not names for these two positions.
