Answer:
D. A
General Formulas and Concepts:
Simple Harmonic Motion
Parts of a wave
- Period
- Amplitude
- Wavelength
- Crest/Trough
Step-by-step explanation:
The amplitude is the distance from the horizon to either the crest or trough of a wave.
In layman's terms, it is how high the wave is.
The "highest" wave would be wave A.
∴ our answer is D.
