Wave trough refers to the:
Correct answer: D. Lowest point of the wave
- A. Wave length
- B. Wave speed
- C. Highest point of the wave
- D. Lowest point of the wave
Explanation
The correct statement is D. Lowest point of the wave. The trough is the lowest point in a wave where the displacement of the medium is at its minimum.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
