Show answer & explanation
Correct answer: A
The diagram represents a waveform — a graphical plot showing how a quantity (for sound, usually air pressure or particle displacement) varies over time. Amplitude: Maximum displacement from the equilibrium (vertical axis).
Period: Time (or horizontal distance) between successive similar points on the wave (e.g., crest to crest); frequency is the inverse of period.
Crest: The highest point of the wave.
Trough: The lowest point of the wave.
